## 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.

Utility method for extruding a bounding box.

  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

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

|  | HardwareIndexBufferSharedPtr | indexBuffer,
|  | const Light * | light,

|  | 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

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.

virtual void Ogre::MovableObject::setQueryFlags | ( | unsigned long | 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 181 of file OgreMovableObject.h.

void Ogre::MovableObject::setRenderQueueGroup | ( | RenderQueueGroupID | 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.

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

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.

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

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
