Shiny balls with OpenGL

Hi, anyone done interesting things with ruby-opengl?

Made some lit spheres: http://dark.fhtr.org...
(needs ruby-opengl and glut)

Seems like it'd be quite feasible to use Ruby for managing the scene and
write the heavy drawing functions in C for speed. (Or precalc to display
lists)

Hi, I enjoyed it!
3 changes made it more comfortable for me to look at: I changed the
2nd parameter in gluLookAt (in set_camera() ) from 2.0 to 4.0 (the
y-coord of the eye) to back off and see the whole setup of the spheres.
Also, I divided the time value in set_camera() and draw_lights() by
10.0 to smooth out the animation.
Thanks for sharing the code!
