[x3d-public] Calculations for scenes

Look into HAnim, Rigid Body Physics, Collisions, Volume Rendering, Particle
Systems.  Ray Tracing and Ray Marching are pretty standard for finding
intersections and computing lighting, and some solutions include gridding
or octrees.   I don’t know if there’s a standard for “global illumination”
yet.   Things are moving towards PBR solutions.

OC, there’s lots of areas to investigate!   Maybe look into quantum
lighting effects?   Maybe try to solve hard math problems in quantum

It gets a lot easier if you try to focus on one domain instead of generic
systems.   Choose what interests you!

Im I’m guessing you’re referring to NP solutions to math problems?
