hi

I have problems with GLSelect picking.

The call
1  
gl.glDrawElements(mode, igeoArray.getValidIndexCount(), GL.GL_UNSIGNED_INT, buffer);

in org.xith3d.render.jsr231.ShapeAtomPeer takes extremely long in GLSelect mode.

Does anyone have any idea, why?

AFAIK, GL_SELECT has always been extremely slow. Color-coding is much faster.

(render scene with solid colors, pick 1 pixel, clear framebuffers, render scene with usual shading)

Thanks. I'll read about it in the net and try it out.
