Could someone point me to a source for OpenGL* data plotting routines? I mean basic things like drawing axis labels on a 3D data plot, flow vector arrows, and so forth. The sort of things that take some fiddling with to get a decent appearance. I’d rather not spend time re-inventing various wheels, but this plotting needs to be embedded in larger code, so an external plotting app is not really an option.
C code with OpenGL calls would be best, but readily-translatable move/draw commands in any C-ish language would be a step up from coding from scratch.
