Zhu3D is an interactive OpenGL-based mathematical function viewer. You can visualize functions, parametric systems and isosurfaces. The viewer supports special effects like animation, morphing, transparency, textures, fog and motion blur.
Includes a benchmark that takes 5 seconds, results with my rig:
GPU = 1443 FPS (Nvidia 8800 GTX)
CPU = 400 Isomarks (Intel Q9450 @ 3.2GHz)
