## Detailed Description

Definition of a Plane that may be attached to a node, and the derived details of it retrieved simply.

Remarks:
  This plane is not here for rendering purposes, it's to allow you to attach planes to the scene in order to have them move and follow nodes on their own, which is useful if you're using the plane for some kind of calculation, e.g. reflection.

Referenced by Ogre::PlaneBoundedVolume::intersects().

Side Ogre::Plane::getSide | ( | const AxisAlignedBox & | rkBox | ) | const`[inherited]`

returns the side where the aligneBox is.

the flag BOTH_SIDE indicates an intersecting box. one corner ON the plane is sufficient to consider the box and the plane intersecting.

Side Ogre::Plane::getSide | ( | const Vector3 & | centre,
|  | const Vector3 & | halfSize |
| ) |  |  | const`[inherited]`

Returns which side of the plane that the given box lies on.

The box is defined as centre/half-size pairs for effectively.

Parameters:

  | centre | The centre of the box.
  | halfSize | The half-size of the box.

Returns:
  POSITIVE_SIDE if the box complete lies on the "positive side" of the plane, NEGATIVE_SIDE if the box complete lies on the "negative side" of the plane, and BOTH_SIDE if the box intersects the plane.

Real Ogre::Plane::getDistance | ( | const Vector3 & | rkPoint | ) | const`[inherited]`

This is a pseudodistance.

The sign of the return value is positive if the point is on the positive side of the plane, negative if the point is on the negative side, and zero if the point is on the plane.

  The absolute value of the return value is the true distance only when the plane normal is a unit length vector.

Remarks:
  This gives you the element of the input vector that is perpendicular to the normal of the plane. You can get the element which is parallel to the normal of the plane by subtracting the result of this method from the original vector, since parallel + perpendicular = original.

Parameters:

  | v | The input vector

Definition at line 173 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 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 bool Ogre::MovableObject::isVisible | ( | void |  | ) | const`[virtual, inherited]`

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

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

Reimplemented in Ogre::InstancedGeometry::BatchInstance, and Ogre::StaticGeometry::Region.

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.

Definition at line 290 of file OgreMovableObject.h.

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.

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.

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
