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

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

void Ogre::ShadowCaster::generateShadowVolume EdgeData   edgeData,

const Light   light,

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.

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.

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 RENDER_QUEUE_MAIN 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]
 

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.

void Ogre::MovableObject::setVisible bool    visible [virtual, inherited]
 

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

Reimplemented in Ogre::Light.

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::GuiElement, Ogre::Rectangle2D, and Ogre::BorderRenderable.

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::GuiElement, Ogre::Rectangle2D, and Ogre::BorderRenderable.
