Definition at line 668 of file OgreFrustum.cpp.

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.

void Ogre::Frustum::enableCustomNearClipPlane const Plane   plane [virtual]
 

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.
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.

void Ogre::Frustum::enableCustomNearClipPlane const MovablePlane   plane [virtual]
 

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).

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.

void Ogre::Frustum::enableReflection const MovablePlane   p [virtual]
 

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.

void Ogre::ShadowCaster::extrudeBounds AxisAlignedBox   box,

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

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.

Remarks:

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.

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 170 of file OgreRenderable.h.

void Ogre::Frustum::setFarClipDistance Real    farDist [virtual]
 

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.

void Ogre::Frustum::setFOVy const Radian   fovy [virtual]
 

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.

Referenced by Ogre::SceneManager::prepareShadowTextures().

void Ogre::Frustum::setNearClipDistance Real    nearDist [virtual]
 

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.

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 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.
