Box2D has functions to compute contact points for overlapping shapes. If we consider circle-circle or circle-polygon, we can only get one contact point and normal. In the case of polygon-polygon we can get two points. These points share the same normal vector so Box2D groups them into a manifold structure. georgia water and fire restoration roswell gaWebNon-manifold topology polygons have a configuration that cannot be unfolded into a continuous flat piece.
