Detailed Description

DepthShadowRecieverRenderTechnique used in an OGRE environment.

This technique defines that the object will recieve shadows with the help of depth shadow maps. Each lightsource can have a depth map assigned to it. These are going to be refreshed only if shadow recievers are visible. It is the shadow reciever technique's resposibility to refresh them.

The shadows from each light are calculated in separate passes. Each pass will modulate the shaded image, so thes should be the last passes (but before caustic passes). The given Pass* parameter n the constructor defines the pass after which new shadow recieving passes will be added by the technique.

Member Function Documentation

void OgreDepthShadowRecieverRenderTechnique::update (  unsigned long  frameNum  )  [virtual]

Updates the resources in the given frame. A RenderTechnique is usually need some resources from several runs, so these runs will be updated. Parameters: frameNum  the actual framenumber Reimplemented from RenderTechnique.
