## Detailed Description

A viewpoint from which the scene will be rendered.

Remarks:
  OGRE renders scenes from a camera viewpoint into a buffer of some sort, normally a window or a texture (a subclass of RenderTarget). OGRE cameras support both perspective projection (the default, meaning objects get smaller the further away they are) and orthographic projection (blueprint-style, no decrease in size with distance). Each camera carries with it a style of rendering, e.g. full textured, flat shaded, wireframe), field of view, rendering distances etc, allowing you to use OGRE to create complex multi-window views if required. In addition, more than one camera can point at a single render target if required, each rendering to a subset of the target, allowing split screen and picture-in-picture views.

  Cameras maintain their own aspect ratios, field of view, and frustrum, and project co-ordinates into a space measured from -1 to 1 in x and y, and 0 to 1 in z. At render time, the camera will be rendering to a Viewport which will translate these parametric co-ordinates into real screen co-ordinates. Obviously it is advisable that the viewport has the same aspect ratio as the camera to avoid distortion (unless you want it!).

  Note that a Camera can be attached to a SceneNode, using the method SceneNode::attachObject. If this is done the Camera will combine it's own position/orientation settings with it's parent SceneNode. This is useful for implementing more complex Camera / object relationships i.e. having a camera attached to a world object.

Sets the camera's direction vector.

Vector3 Ogre::Camera::getDirection | ( | void |  | ) | const

|  | Real | y,
|  | Real | z |
| ) |  |  |

Points the camera at a location in worldspace.

Remarks:

void Ogre::Camera::setFixedYawAxis | ( | bool | useFixed,
|  | const Vector3 & | fixedAxis = `Vector3::UNIT_Y` |
| ) |  |  |

Tells the camera whether to yaw around it's own local Y axis or a fixed axis of choice.

Remarks:
  This method allows you to change the yaw behaviour of the camera
  - by default, the camera yaws around a fixed Y axis. This is often what you want - for example if you're making a first-person shooter, you really don't want the yaw axis to reflect the local camera Y, because this would mean a different yaw axis if the player is looking upwards rather than when they are looking straight ahead. You can change this behaviour by calling this method, which you will want to do if you are making a completely free camera like the kind used in a flight simulator.

Parameters:

  | useFixed | If true, the axis passed in the second parameter will always be the yaw axis no matter what the camera orientation. If false, the camera yaws around the local Y.
  | fixedAxis | The axis to use if the first parameter is true.

const String& Ogre::Camera::getMovableType | ( | void |  | ) | const`[virtual]`

Overridden from MovableObject.

Reimplemented from Ogre::Frustum.

void Ogre::Camera::setAutoTracking | ( | bool | enabled,
|  | SceneNode * | target = `0`,
|  | const Vector3 & | offset = `Vector3::ZERO` |
| ) |  |  |

Enables / disables automatic tracking of a SceneNode.

Remarks:
  If you enable auto-tracking, this Camera will automatically rotate to look at the target SceneNode every frame, no matter how it or SceneNode move. This is handy if you want a Camera to be focused on a single object or group of objects. Note that by default the Camera looks at the origin of the SceneNode, if you want to tweak this, e.g. if the object which is attached to this target node is quite big and you want to point the camera at a specific point on it, provide a vector in the 'offset' parameter and the camera's target point will be adjusted.

Parameters:

  | enabled | If true, the Camera will track the SceneNode supplied as the next parameter (cannot be null). If false the camera will cease tracking and will remain in it's current orientation.
  | target | Pointer to the SceneNode which this Camera will track. Make sure you don't delete this SceneNode before turning off tracking (e.g. SceneManager::clearScene will delete it so be careful of this). Can be null if and only if the enabled param is false.
  | offset | If supplied, the camera targets this point in local space of the target node instead of the origin of the target node. Good for fine tuning the look at point.

void Ogre::Camera::setLodBias | ( | Real | factor = `1.0` | ) |

Sets the level-of-detail factor for this Camera.

Remarks:
  This method can be used to influence the overall level of detail of the scenes rendered using this camera. Various elements of the scene have level-of-detail reductions to improve rendering speed at distance; this method allows you to hint to those elements that you would like to adjust the level of detail that they would normally use (up or down).

  The most common use for this method is to reduce the overall level of detail used for a secondary camera used for sub viewports like rear-view mirrors etc. Note that scene elements are at liberty to ignore this setting if they choose, this is merely a hint.

Parameters:

  | factor | The factor to apply to the usual level of detail calculation. Higher values increase the detail, so 2.0 doubles the normal detail and 0.5 halves it.

Real Ogre::Camera::getLodBias | ( | void |  | ) | const

Returns the level-of-detail bias factor currently applied to this camera.

Remarks:
  See Camera::setLodBias for more details.

Ray Ogre::Camera::getCameraToViewportRay | ( | Real | screenx,
|  | Real | screeny |
| ) |  |  | const

Real Ogre::Camera::_getLodBiasInverse | ( | void |  | ) | const

Internal method for OGRE to use for LOD calculations.

void Ogre::Camera::_autoTrack | ( | void |  | ) |

Internal method used by OGRE to update auto-tracking cameras.

virtual void Ogre::Camera::setWindow | ( | Real | Left,
|  | Real | Top,
|  | Real | Right,
|  | Real | Bottom |
| ) |  |  | `[virtual]`

Sets the viewing window inside of viewport.

Remarks:
  This method can be used to set a subset of the viewport as the rendering target.

Parameters:

  | Left | Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 0).
  | Top | Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 0).
  | Right | Relative to Viewport - 0 corresponds to left edge, 1 - to right edge (default - 1).
  | Bottom | Relative to Viewport - 0 corresponds to top edge, 1 - to bottom edge (default - 1).

virtual void Ogre::Camera::resetWindow | ( | void |  | ) | `[virtual]`

Notifies this camera that a viewport is using it.

Definition at line 488 of file OgreCamera.h.

void Ogre::Camera::setAutoAspectRatio | ( | bool | autoratio | ) |

If set to true a vieport that owns this frustum will be able to recalculate the aspect ratio whenever the frustum is resized.

Remarks:
  You should set this to true only if the frustum / camera is used by one viewport at the same time. Otherwise the aspect ratio for other viewports may be wrong.

bool Ogre::Camera::getAutoAspectRatio | ( | void |  | ) | const

Retreives if AutoAspectRatio is currently set or not.

void Ogre::Camera::setCullingFrustum | ( | Frustum * | frustum | ) |

Tells the camera to use a separate Frustum instance to perform culling.

Remarks:
  By calling this method, you can tell the camera to perform culling against a different frustum to it's own. This is mostly useful for debug cameras that allow you to show the culling behaviour of another camera, or a manual frustum instance.

Parameters:

  | frustum | Pointer to a frustum to use; this can either be a manual Frustum instance (which you can attach to scene nodes like any other MovableObject), or another camera. If you pass 0 to this method it reverts the camera to normal behaviour.

Definition at line 514 of file OgreCamera.h.

Frustum* Ogre::Camera::getCullingFrustum | ( | void |  | ) |

| ) |  |  | const`[virtual]`

Tests whether the given container is visible in the Frustum.

Parameters:

  | bound | Bounding box to be checked (world space)

Remarks:
  The corners are ordered as follows: top-right near, top-left near, bottom-left near, bottom-right near, top-right far, top-left far, bottom-left far, bottom-right far.

Reimplemented from Ogre::Frustum.

const Plane& Ogre::Camera::getFrustumPlane | ( | unsigned short | plane | ) | const`[virtual]`

bool Ogre::Camera::projectSphere | ( | const Sphere & | sphere,
|  | Real * | left,
|  | Real * | top,
|  | Real * | right,
|  | Real * | bottom |
| ) |  |  | const`[virtual]`

Reimplemented from Ogre::Frustum.

const Matrix4& Ogre::Camera::getViewMatrix | ( | bool | ownFrustumOnly | ) | const

Specialised version of getViewMatrix allowing caller to differentiate whether the custom culling frustum should be allowed or not.

Remarks:
  The default behaviour of the standard getViewMatrix is to delegate to the alternate culling frustum, if it is set. This is expected when performing CPU calculations, but the final rendering must be performed using the real view matrix in order to display the correct debug view.

virtual void Ogre::Camera::setUseRenderingDistance | ( | bool | use | ) | `[virtual]`

Set whether this camera should use the 'rendering distance' on objects to exclude distant objects from the final image.

The default behaviour is to use it.

virtual void Ogre::Frustum::updateWorldSpaceCornersImpl | ( | void |  | ) | const`[protected, virtual, inherited]`

Implementation of updateWorldSpaceCorners (called if out of date).

virtual void Ogre::Frustum::updateVertexData | ( | void |  | ) | const`[protected, virtual, inherited]`

virtual bool Ogre::Frustum::isFrustumOutOfDate | ( | void |  | ) | const`[protected, virtual, inherited]`

virtual void Ogre::Frustum::setFOVy | ( | const Radian & | fovy | ) | `[virtual, inherited]`

Sets the Y-dimension Field Of View (FOV) of the frustum.

Remarks:
  Field Of View (FOV) is the angle made between the frustum's position, and the edges of the 'screen' onto which the scene is projected. High values (90+ degrees) result in a wide-angle, fish-eye kind of view, low values (30- degrees) in a stretched, telescopic kind of view. Typical values are between 45 and 60 degrees.

  This value represents the VERTICAL field-of-view. The horizontal field of view is calculated from this depending on the dimensions of the viewport (they will only be the same if the viewport is square).

Note:
  Setting the FOV overrides the value supplied for frustum::setNearClipPlane.

virtual const Radian& Ogre::Frustum::getFOVy | ( | void |  | ) | const`[virtual, inherited]`

Retrieves the frustums Y-dimension Field Of View (FOV).

virtual void Ogre::Frustum::setNearClipDistance | ( | Real | nearDist | ) | `[virtual, inherited]`

Sets the position of the near clipping plane.

Remarks:
  The position of the near clipping plane is the distance from the frustums position to the screen on which the world is projected. The near plane distance, combined with the field-of-view and the aspect ratio, determines the size of the viewport through which the world is viewed (in world co-ordinates). Note that this world viewport is different to a screen viewport, which has it's dimensions expressed in pixels. The frustums viewport should have the same aspect ratio as the screen viewport it renders into to avoid distortion.

Parameters:

  | near | The distance to the near clipping plane from the frustum in world coordinates.

virtual void Ogre::Frustum::setFarClipDistance | ( | Real | farDist | ) | `[virtual, inherited]`

Sets the distance to the far clipping plane.

Remarks:
  The view frustrum is a pyramid created from the frustum position and the edges of the viewport. This method sets the distance for the far end of that pyramid. Different applications need different values: e.g. a flight sim needs a much further far clipping plane than a first-person shooter. An important point here is that the larger the ratio between near and far clipping planes, the lower the accuracy of the Z-buffer used to depth-cue pixels. This is because the Z-range is limited to the size of the Z buffer (16 or 32-bit) and the max values must be spread over the gap between near and far clip planes. As it happens, you can affect the accuracy far more by altering the near distance rather than the far distance, but keep this in mind.

Parameters:

  | far | The distance to the far clipping plane from the frustum in world coordinates.If you specify 0, this means an infinite view distance which is useful especially when projecting shadows; but be careful not to use a near distance too close.

virtual void Ogre::Frustum::setAspectRatio | ( | Real | ratio | ) | `[virtual, inherited]`

Sets the aspect ratio for the frustum viewport.

Remarks:
  The ratio between the x and y dimensions of the rectangular area visible through the frustum is known as aspect ratio: aspect = width / height .

  The default for most fullscreen windows is 1.3333 - this is also assumed by Ogre unless you use this method to state otherwise.

virtual Real Ogre::Frustum::getAspectRatio | ( | void |  | ) | const`[virtual, inherited]`

Retreives the current aspect ratio.

virtual void Ogre::Frustum::setFrustumOffset | ( | const Vector2 & | offset | ) | `[virtual, inherited]`

Sets frustum offsets, used in stereo rendering.

Remarks:
  You can set both horizontal and vertical plane offsets of "eye"; in stereo rendering frustum is moved in horizontal plane. To be able to render from two "eyes" you'll need two cameras rendering on two RenderTargets.

  The frustum offsets is in world coordinates, and default to (0, 0) - no offsets.

Parameters:

  | offset | The horizontal and vertical plane offsets.

virtual void Ogre::Frustum::setFrustumOffset | ( | Real | horizontal = `0.0`,
|  | Real | vertical = `0.0` |
| ) |  |  | `[virtual, inherited]`

Sets frustum offsets, used in stereo rendering.

Remarks:
  You can set both horizontal and vertical plane offsets of "eye"; in stereo rendering frustum is moved in horizontal plane. To be able to render from two "eyes" you'll need two cameras rendering on two RenderTargets.

  The frustum offsets is in world coordinates, and default to (0, 0) - no offsets.

Parameters:

  | horizontal | The horizontal plane offset.
  | vertical | The vertical plane offset.

virtual const Vector2& Ogre::Frustum::getFrustumOffset | ( |  | ) | const`[virtual, inherited]`

Retreives the frustum offsets.

virtual void Ogre::Frustum::setFocalLength | ( | Real | focalLength = `1.0` | ) | `[virtual, inherited]`

Sets frustum focal length (used in stereo rendering).

Parameters:

  | focalLength | The distance to the focal plane from the frustum in world coordinates.

virtual Real Ogre::Frustum::getFocalLength | ( |  | ) | const`[virtual, inherited]`

Returns focal length of frustum.

virtual const Matrix4& Ogre::Frustum::getProjectionMatrixRS | ( | void |  | ) | const`[virtual, inherited]`

Gets the projection matrix for this frustum adjusted for the current rendersystem specifics (may be right or left-handed, depth range may vary).

Remarks:
  This method retrieves the rendering-API dependent version of the projection matrix. If you want a 'typical' projection matrix then use getProjectionMatrix.

virtual const Matrix4& Ogre::Frustum::getProjectionMatrixWithRSDepth | ( | void |  | ) | const`[virtual, inherited]`

Gets the depth-adjusted projection matrix for the current rendersystem, but one which still conforms to right-hand rules.

Remarks:
  This differs from the rendering-API dependent getProjectionMatrix in that it always returns a right-handed projection matrix result no matter what rendering API is being used - this is required for vertex and fragment programs for example. However, the resulting depth range may still vary between render systems since D3D uses [0,1] and GL uses [-1,1], and the range must be kept the same between programmable and fixed-function pipelines.

virtual const Matrix4& Ogre::Frustum::getProjectionMatrix | ( | void |  | ) | const`[virtual, inherited]`

Gets the normal projection matrix for this frustum, ie the projection matrix which conforms to standard right-handed rules and uses depth range [-1,+1].

Remarks:
  This differs from the rendering-API dependent getProjectionMatrixRS in that it always returns a right-handed projection matrix with depth range [-1,+1], result no matter what rendering API is being used - this is required for some uniform algebra for example.

virtual void Ogre::Frustum::setCustomViewMatrix | ( | bool | enable,
|  | const Matrix4 & | viewMatrix = `Matrix4::IDENTITY` |
| ) |  |  | `[virtual, inherited]`

Set whether to use a custom view matrix on this frustum.

Remarks:
  This is an advanced method which allows you to manually set the view matrix on this frustum, rather than having it calculate itself based on it's position and orientation.

Note:
  After enabling a custom view matrix, the frustum will no longer update on its own based on position / orientation changes. You are completely responsible for keeping the view matrix up to date. The custom matrix will be returned from getViewMatrix.

Parameters:

  | enable | If true, the custom view matrix passed as the second parameter will be used in preference to an auto calculated one. If false, the frustum will revert to auto calculating the view matrix.
  | viewMatrix | The custom view matrix to use, the matrix must be an affine matrix.

virtual void Ogre::Frustum::setCustomProjectionMatrix | ( | bool | enable,
|  | const Matrix4 & | projectionMatrix = `Matrix4::IDENTITY` |
| ) |  |  | `[virtual, inherited]`

Set whether to use a custom projection matrix on this frustum.

Remarks:
  This is an advanced method which allows you to manually set the projection matrix on this frustum, rather than having it calculate itself based on it's position and orientation.

Note:
  After enabling a custom projection matrix, the frustum will no longer update on its own based on field of view and near / far distance changes. You are completely responsible for keeping the projection matrix up to date if those values change. The custom matrix will be returned from getProjectionMatrix and derivative functions.

Parameters:

  | enable | If true, the custom projection matrix passed as the second parameter will be used in preference to an auto calculated one. If false, the frustum will revert to auto calculating the projection matrix.
  | projectionMatrix | The custom view matrix to use

See also:
  Frustum::setCustomViewMatrix

Returns whether or not this object is supposed to be visible or not.

Remarks:
  Takes into account both upper rendering distance and visible flag.

virtual void Ogre::Frustum::enableReflection | ( | const Plane & | p | ) | `[virtual, inherited]`

Modifies this frustum so it always renders from the reflection of itself through the plane specified.

Remarks:
  This is obviously useful for performing planar reflections.

virtual void Ogre::Frustum::enableReflection | ( | const MovablePlane * | p | ) | `[virtual, inherited]`

Modifies this frustum so it always renders from the reflection of itself through the plane specified.

Note that this version of the method links to a plane so that changes to it are picked up automatically. It is important that this plane continues to exist whilst this object does; do not destroy the plane before the frustum.

Remarks:
  This is obviously useful for performing planar reflections.

Definition at line 514 of file OgreFrustum.h.

virtual void Ogre::Frustum::enableCustomNearClipPlane | ( | const MovablePlane * | plane | ) | `[virtual, inherited]`

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks:
  There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts). Whilst it is possible to use user clip planes, they are not supported on all cards, and sometimes are not hardware accelerated when they are available. Instead, where a single clip plane is involved, this technique uses a 'fudging' of the near clip plane, which is available and fast on all hardware, to perform as the arbitrary clip plane. This does change the shape of the frustum, leading to some depth buffer loss of precision, but for many of the uses of this technique that is not an issue.

  This version of the method links to a plane, rather than requiring a by-value plane definition, and therefore you can make changes to the plane (e.g. by moving / rotating the node it is attached to) and they will automatically affect this object.

Note:
  This technique only works for perspective projection.

Parameters:

  | plane | The plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

virtual void Ogre::Frustum::enableCustomNearClipPlane | ( | const Plane & | plane | ) | `[virtual, inherited]`

Links the frustum to a custom near clip plane, which can be used to clip geometry in a custom manner without using user clip planes.

Remarks:
  There are several applications for clipping a scene arbitrarily by a single plane; the most common is when rendering a reflection to a texture, and you only want to render geometry that is above the water plane (to do otherwise results in artefacts).

Parameters:

  | plane | The plane to link to to perform the clipping. This plane must continue to exist while the camera is linked to it; do not destroy it before the frustum.

virtual void Ogre::Frustum::disableCustomNearClipPlane | ( | void |  | ) | `[virtual, inherited]`

Disables any custom near clip plane.

virtual bool Ogre::Frustum::isCustomNearClipPlaneEnabled | ( | void |  | ) | const`[virtual, inherited]`

Definition at line 170 of file OgreMovableObject.h.

virtual Node* Ogre::MovableObject::getParentNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the scene node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

virtual void Ogre::MovableObject::_notifyAttached | ( | Node * | parent,
|  | bool | isTagPoint = `false` |
| ) |  |  | `[virtual, inherited]`

Internal method called to notify the object that it has been attached to a node.

Reimplemented in Ogre::Entity, Ogre::Light, and Ogre::ParticleSystem.

virtual bool Ogre::MovableObject::isAttached | ( | void |  | ) | const`[virtual, inherited]`

Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene | ( | void |  | ) | const`[virtual, inherited]`

Internal method called to notify the object that it has been moved.

Reimplemented in Ogre::Light.

virtual const AxisAlignedBox& Ogre::MovableObject::getWorldBoundingBox | ( | bool | derive = `false` | ) | const`[virtual, inherited]`

Retrieves the axis-aligned bounding box for this object in world coordinates.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity.

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere | ( | bool | derive = `false` | ) | const`[virtual, inherited]`

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

Tells this object whether to be visible or not, if it has a renderable component.

Note:
  An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual bool Ogre::MovableObject::getVisible | ( | void |  | ) | const`[virtual, inherited]`

Gets this object whether to be visible or not, if it has a renderable component.

Remarks:
  Returns the value set by MovableObject::setVisible only.

virtual void Ogre::MovableObject::setRenderingDistance | ( | Real | dist | ) | `[virtual, inherited]`

Sets the distance at which the object is no longer rendered.

Parameters:

  | dist | Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 272 of file OgreMovableObject.h.

virtual Real Ogre::MovableObject::getRenderingDistance | ( | void |  | ) | const`[virtual, inherited]`

Gets the distance at which batches are no longer rendered.

Definition at line 278 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 286 of file OgreMovableObject.h.

virtual UserDefinedObject* Ogre::MovableObject::getUserObject | ( | void |  | ) | `[virtual, inherited]`

Retrieves a pointer to a custom application object associated with this movable by an earlier call to setUserObject.

References Ogre::any_cast().

virtual void Ogre::MovableObject::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
  This value is shared with setUserObject so don't use both!

Definition at line 302 of file OgreMovableObject.h.

virtual const Any& Ogre::MovableObject::getUserAny | ( | void |  | ) | const`[virtual, inherited]`

Retrieves the custom user value associated with this object.

Definition at line 306 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup | ( | uint8 | queueID | ) | `[virtual, inherited]`

Sets the render queue group this entity will be rendered through.

Remarks:
  Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

  See RenderQueue for more details.

Parameters:

  | queueID | Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual uint8 Ogre::MovableObject::getRenderQueueGroup | ( | void |  | ) | const`[virtual, inherited]`

Gets the queue group for this entity, see setRenderQueueGroup for full details.

virtual const Matrix4& Ogre::MovableObject::_getParentNodeFullTransform | ( | void |  | ) | const`[virtual, inherited]`

return the full transformation of the parent sceneNode or the attachingPoint node

virtual void Ogre::MovableObject::setQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the query flags for this object.

Remarks:
  When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 334 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

Definition at line 353 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the visiblity flags for this object.

Remarks:
  As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 362 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Definition at line 381 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setListener | ( | Listener * | listener | ) | `[virtual, inherited]`

Sets a listener for this object.

Remarks:
  Note for size and performance reasons only one listener per object is allowed.

Definition at line 388 of file OgreMovableObject.h.

virtual Listener* Ogre::MovableObject::getListener | ( | void |  | ) | const`[virtual, inherited]`

Gets the current listener for this object.

Definition at line 392 of file OgreMovableObject.h.

virtual const LightList& Ogre::MovableObject::queryLights | ( | void |  | ) | const`[virtual, inherited]`

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks:
  By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

  The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also:
  SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

  This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns:
  The list of lights use to lighting this object.

EdgeData* Ogre::MovableObject::getEdgeList | ( | void |  | ) | `[virtual, inherited]`

Define a default implementation of method from ShadowCaster which implements no shadows.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity, Ogre::ManualObject, and Ogre::StaticGeometry::Region.

| ) |  |  | const`[virtual, inherited]`

Overridden member from ShadowCaster.

Implements Ogre::ShadowCaster.

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

Sets whether or not this object will cast shadows.

Remarks:
  This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
  This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 440 of file OgreMovableObject.h.

bool Ogre::MovableObject::getCastShadows | ( | void |  | ) | const`[virtual, inherited]`

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

Definition at line 442 of file OgreMovableObject.h.

Real Ogre::MovableObject::getPointExtrusionDistance | ( | const Light * | l | ) | const`[virtual, inherited]`

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

virtual uint32 Ogre::MovableObject::getTypeFlags | ( | void |  | ) | const`[virtual, inherited]`

Get the 'type flags' for this MovableObject.

Remarks:
  A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::Light, Ogre::ParticleSystem, and Ogre::StaticGeometry::Region.

static void Ogre::ShadowCaster::extrudeVertices | ( | const HardwareVertexBufferSharedPtr & | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist |
| ) |  |  | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

  | vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  | originalVertexCount | The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

Real Ogre::ShadowCaster::getExtrusionDistance | ( | const Vector3 & | objectPos,
|  | const Light * | light |
| ) |  |  | const`[protected, inherited]`

Helper moethod for calculating extrusion distance.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos |
| ) |  |  | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  | edgeData | The edge information to update
  | lightPos | 4D vector representing the light, a directional light has w=0.0

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | const HardwareIndexBufferSharedPtr & | indexBuffer,
|  | const Light * | light,
|  | ShadowRenderableList & | shadowRenderables,
|  | unsigned long | flags |
| ) |  |  | `[protected, virtual, inherited]`

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

  | edgeData | The edge information to use
  | indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  | light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
  | shadowRenderables | A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
  | flags | Additional controller flags, see ShadowRenderableFlags

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist |
| ) |  |  | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  | box | Original bounding box, will be updated in-place
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

virtual const String& Ogre::AnimableObject::getAnimableDictionaryName | ( | void |  | ) | const`[protected, virtual, inherited]`

Get the name of the animable dictionary for this class.

Remarks:
  Subclasses must override this if they want to support animation of their values.

virtual Technique* Ogre::Renderable::getTechnique | ( | void |  | ) | const`[virtual, inherited]`

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:
  This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms | ( | void |  | ) | const`[virtual, inherited]`

Returns the number of world transform matrices this renderable requires.

Remarks:
  When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

void Ogre::Renderable::setUseIdentityProjection | ( | bool | useIdentityProjection | ) | `[inherited]`

Sets whether or not to use an 'identity' projection.

Remarks:
  Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.

void Ogre::Renderable::setUseIdentityView | ( | bool | useIdentityView | ) | `[inherited]`

Sets whether or not to use an 'identity' view.

Remarks:
  Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

void Ogre::Renderable::setCustomParameter | ( | size_t | index,
|  | const Vector4 & | value |
| ) |  |  | `[inherited]`

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
  Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.

Parameters:

  | index | The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
  | value | The value to associate.

Definition at line 204 of file OgreRenderable.h.

const Vector4& Ogre::Renderable::getCustomParameter | ( | size_t | index | ) | const`[inherited]`

virtual void Ogre::Renderable::_updateCustomGpuParameter | ( | const GpuProgramParameters::AutoConstantEntry & | constantEntry,
|  | GpuProgramParameters * | params |
| ) |  |  | const`[virtual, inherited]`

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
  This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

  You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters:

  | constantEntry | The auto constant entry referring to the parameter being updated
  | params | The parameters object which this method should call to set the updated parameters.
