Hi,

for my water-simulation I need some kind of Clipping-Planes. Not only because of performance issues, but also for correct displaying of the reflection-/refraction-map. At the moment I use a work-around in which the shader discards all fragments, which have a certain height. This works quite nice, but anyhow the shader processes all vertices, which takes time and more worse the vertex-shader for shadow mapping also generates more info. This leads to a enormous consumption of rendering time at shadow-processing.

So is there a possibility to have individual user-clip-planes per pipeline-stage in horde?

Thanks

AFAIK no. But maybe you can adjust the camera projection matrix as mentioned in this paper to have a user defined clipping plane.

Hi Volker,
thanks for your post Too bad, that horde can't do that
Just had a quick look at the paper, seems very promising to me. Hopefully I can understand the mathematics behind that
