virtual void Ogre::SimpleRenderable::_notifyCurrentCamera | ( | Camera * | cam | ) | `[virtual, inherited]`

Internal method to notify the object of the camera to be used for the next rendering operation.

Remarks:

Reimplemented from Ogre::MovableObject.

virtual void Ogre::MovableObject::_notifyManager | ( | SceneManager * | man | ) | `[virtual, inherited]`

| Notify the object of it's manager (internal use only). Definition at line 111 of file OgreMovableObject.h.

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.

Reimplemented in Ogre::SubEntity, and Ogre::TerrainRenderable.

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

static void Ogre::ShadowCaster::extrudeVertices | ( | 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

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | HardwareIndexBufferSharedPtr | indexBuffer,
|  | const Light * | light,

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

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, Ogre::StaticGeometry::Region, and Ogre::TerrainRenderable.

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

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

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.

| Reimplemented from Ogre::SimpleRenderable.

void Ogre::WireBoundingBox::getWorldTransforms | ( | Matrix4 * | xform | ) | const`[protected, virtual]`

| Override this method to prevent parent transforms (rotation,translation,scale). Reimplemented from Ogre::SimpleRenderable.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary | ( | StringVector & | vec | ) | const`[protected, virtual, inherited]`

| Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters. Reimplemented in Ogre::Light. Definition at line 248 of file OgreAnimable.h.

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]`

| Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

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::StaticGeometry::Region.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 281 of file OgreMovableObject.h.

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

| As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 309 of file OgreMovableObject.h.

void Ogre::SimpleRenderable::setBoundingBox | ( | const AxisAlignedBox & | box | ) | `[inherited]`

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 346 of file OgreMovableObject.h.

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 167 of file OgreRenderable.h.

static void Ogre::MovableObject::setDefaultQueryFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default query flags for all future MovableObject instances. Definition at line 288 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultVisibilityFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default visibility flags for all future MovableObject instances. Definition at line 316 of file OgreMovableObject.h.

void Ogre::SimpleRenderable::setMaterial | ( | const String & | matName | ) | `[inherited]`

virtual void Ogre::Renderable::setPolygonModeOverrideable | ( | bool | override | ) | `[virtual, inherited]`

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:

  | override | true means that a lower camera detail will override this renderables detail level, false means it won't.

Definition at line 231 of file OgreRenderable.h.

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 273 of file OgreMovableObject.h.

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 211 of file OgreMovableObject.h.

virtual void Ogre::SimpleRenderable::setRenderOperation | ( | const RenderOperation & | rend | ) | `[virtual, inherited]`

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.

void Ogre::WireBoundingBox::setupBoundingBox | ( | const AxisAlignedBox & | aabb | ) |

Builds the wireframe line list.

Parameters:

  | aabb | bounding box to build a wireframe from.

void Ogre::WireBoundingBox::setupBoundingBoxVertices | ( | const AxisAlignedBox & | aab | ) | `[protected]`

| Builds the wireframe line list.

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 241 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 225 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 301 of file OgreMovableObject.h.

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.

void Ogre::SimpleRenderable::setWorldTransform | ( | const Matrix4 & | xform | ) | `[inherited]`

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 bool Ogre::Renderable::useIdentityProjection | ( | void |  | ) | const`[virtual, inherited]`

Returns 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 override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.

Definition at line 114 of file OgreRenderable.h.

virtual bool Ogre::Renderable::useIdentityView | ( | void |  | ) | const`[virtual, inherited]`

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

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 override this.

Reimplemented in Ogre::BorderRenderable, Ogre::OverlayElement, and Ogre::Rectangle2D.
