Vertex program extrusion

· by Steve · Read in about 1 min · (169 Words)

I’m currently adding vertex program extrusion into the mix, which is giving me some frame rate improvements with stencil shadows. I also have to sort out infinite far plane projection otherwise in zfail mode the dark caps get culled, since they are being projected to infinity in the vertex program.

I have a weird corruption of the volume when using vertex programs on skeletally animated meshes in release mode right now, that’s puzzling me a little since they’re fine in debug mode and non-animated meshes are fine in release mode. I’ll have to keep digging.

I think I’ll have to rule out depth shadowmaps for the 0.14 release since I won’t have time. At least we have one form of texture shadow in addition to 2 stencil shadow techniques, which is more than other open source engines right now 😉 I’m part-way through writing up a new manual section on the shadows too, since that needs to be ready for the release. So much to do, so little time…
