I am looking for a library which would easily allow me to render shapes (cubes, spheres, lines, circles, etc.) in 3D3 and OpenGL if possible. I want to be able to rapidly design visual debugging tools and I am not proefficient enough in graphics rendering to do it myself (writing the low level stuff that is). The library would have to be for C/C++.
I've already taken a look at the open-source 3d engine, but I feel those are too big for what I really need.
Do any of you know if such library exist? If so, links would be appreciated!
