C# 클래스 Box2D.Collision.ManifoldPoint

A manifold point is a contact point belonging to a contact manifold. It holds details related to the geometry and dynamics of the contact points. The local point usage depends on the manifold type:
  • e_circles: the local center of circleB
  • e_faceA: the local center of cirlceB or the clip point of polygonB
  • e_faceB: the clip point of polygonA
This structure is stored across time steps, so we keep it small.
Note: the impulses are used for internal caching and may not provide reliable contact forces, especially for high speed collisions.
