class	b2Shape

A convex polygon.

const b2Vec2 * b2PolygonShape::GetCoreVertices ( ) const [inline]

Get the core vertices in local coordinates.

These vertices represent a smaller polygon that is used for time of impact computations.

Get the support point in the given world direction.

Use the supplied transform.
