Method Description
CollideCircles ( Manifold &manifold, CircleShape circleA, Transform &xfA, CircleShape circleB, Transform &xfB ) : void
CollideEdgeAndCircle ( Manifold &manifold, EdgeShape edgeA, Transform &transformA, CircleShape circleB, Transform &transformB ) : void

Compute contact points for edge versus circle. This accounts for edge connectivity.
CollideEdgeAndPolygon ( Manifold &manifold, EdgeShape edgeA, Transform &xfA, PolygonShape polygonB, Transform &xfB ) : void

Collides and edge and a polygon, taking into account edge adjacency.
CollidePolygonAndCircle ( Manifold &manifold, PolygonShape polygonA, Transform &transformA, CircleShape circleB, Transform &transformB ) : void

Compute the collision manifold between a polygon and a circle.
CollidePolygons ( Manifold &manifold, PolygonShape polyA, Transform &transformA, PolygonShape polyB, Transform &transformB ) : void

Compute the collision manifold between two polygons.
GetPointStates ( FixedArray2 &state1, FixedArray2 &state2, Manifold &manifold1, Manifold &manifold2 ) : void
GetWorldManifold ( Manifold &manifold, Transform &transformA, float radiusA, Transform &transformB, float radiusB, Vector2 &normal, FixedArray2 &points ) : void

Evaluate the manifold with supplied transforms. This assumes modest motion from the original state. This does not change the point count, impulses, etc. The radii must come from the Shapes that generated the manifold.
