Three-Sphere collision system #28

Closed mattrdowney closed 6 years ago

mattrdowney commented 6 years ago

The intersection of two spheres is a circle, then you just need to do arc checking.

PlanetariaCache will need to be augmented, and collision checks will all need to be deferred to WaitForFixedUpdate for PlanetariaActor.

mattrdowney commented 6 years ago

By using three spheres, the collisions can be limited to just an arc (for most--if not all--arcs on the surface of a sphere).
