Useful for mathematical graphics?

+ Easy to create complex interactive 3d scenes

+ Don't have to think about implementation of lighting, shading, etc

- Not for photorealistic effects (eg raytracing) - Client side, not always easy to set up.

Example: Symmetry group of the cube generated by reflections across 3 mirrors

Start with fundamental domain (Weyl chamber)

Clicking on mirrors moves the fundamental domain (solid region) leaving a trail (transparent regions)
