Hi,
I'd like to query some occlusions with OpenSG... I don't know
if there's any support for this in OpenSG. I'd like to render
a set of points and query their visibility using some OpenGL
query extension. I know how to do that in OpenGL, but I
don't know if I can map that somehow into OpenSG. Here's
a typical loop:
Gluint queries[N];
GLuint pixelCount;
glGenOcclusionQueriesNV(N, queries);
for (i = 0; i < N; i++) {
glBeginOcclusionQueryNV(queries[i]);
// render point i
glEndOcclusionQueryNV();
}
// evaluate visibility...
Any hints?
Regards,
Toni
