| 17 | @brief DepthShadowReceiverRenderTechnique used in an OGRE environment.
|
---|
| 18 |
|
---|
| 19 | This technique defines that the object will recieve shadows with the help of depth shadow maps.
|
---|
| 20 | Each lightsource can have a depth map assigned to it. These are going to be refreshed only
|
---|
| 21 | if shadow receivers are visible. It is the shadow receiver technique's resposibility
|
---|
| 22 | to refresh them.
|
---|
| 23 |
|
---|
| 24 | The shadows from each light are calculated in separate passes. Each pass will
|
---|
| 25 | modulate the shaded image, so thes should be the last passes (but before caustic passes).
|
---|
| 26 | The given Pass* parameter n the constructor defines the pass after which new
|
---|
| 27 | shadow recieving passes will be added by the technique.
