| 17 | @brief CausticReceiverRenderTechnique used in an OGRE environment.
|
---|
| 18 |
|
---|
| 19 | This technique defines that the object will recieve caustic lighting from caustic caster objects.
|
---|
| 20 | The caustic light spots will be calculated by the caustic caster's RenderingRuns.
|
---|
| 21 | These runs will only be updated if caustic redievers are visible, so it is the receiver technique's
|
---|
| 22 | responsibility to update them.
|
---|
| 23 |
|
---|
| 24 | Each caustic caster's light contribution will be added in separate passes. Each pass
|
---|
| 25 | will add some light to the shaded image, so these passes should be the last passes.
|
---|
| 26 | In the constructor the given Pass* parameter will be the pass after which the caustic lighting
|
---|
| 27 | passes will be added by the technique.
