ManifoldPoint Structure |
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:
-ShapeType.Circles: the local center of circleB
-SeparationFunction.FaceA: the local center of cirlceB or the clip point of polygonB
-SeparationFunction.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.
