I believe OpenTK has yet to support this, but I was looking into implementing spheres with OpenGL.
I found this method: Glu.Sphere(), that takes the parameters, int quad, double radius, int slices, int stacks). I'm only using the OpenTK framework for graphics in my project and I know that setting the perspective calls for Glu.Perspective(), so I'm curious as to what this sphere method does or rather is supposed to do, since it doesn't like anything that I've tried to plug in for the integer "quad" parameter.
Anyhow, I don't suppose OpenTK will support preset geometric solids for a while, so I'm in the search of a good tutorial on spheres. Does anyone know of a good, gentle, tutorial on this topic?
