Research Open Source Physics engines

• Motivation: to build something like Research howto implement voxels collisions demo #122 (Voxels collisions)

Do we really need a physics engine? Probably, collision detection is a wide topic.

https://github.com/andyhall/voxel-physics-engine An abstracted physics engine for voxel game engines (javascript)
https://github.com/rustsim/ncollide (Rust collisions)

Collisions in Unity: https://docs.unity3d.com/Manual/PartSysCollisionModule.html

Probably the way to go is to use Unity or Unreal physics engines.

Blender has its own physics engine also: https://docs.blender.org/manual/en/2.79/game_engine/physics/introduction.html

This is the one used in Unity and Unreal, and it is evaluation in Godot (which uses now bullet3) also.
