How to detect a collision between a mesh A and a mesh B if the mesh A completely passed over the mesh B in the frame?
When multiplying the collision normal by the collision depth (returned by EPA), GJK still finds that the meshes are intersecting.
IMO this is a precision error; maybe add a threshold to the collision depth.
Tested with two CircleGeometry having both -50 in their X position.
Cross product between their positions yield a zero vector. The GJK response is correct but the generated simplex is invalid for EPA.
