int32 GetSupport ( const b2Vec2 &  d ) const

inline

Get the supporting vertex index in the given direction.

const b2Vec2 & GetSupportVertex ( const b2Vec2 &  d ) const

inline

Get the supporting vertex in the given direction.

const b2Vec2 & GetVertex ( int32  index ) const

inline

Get a vertex by index. Used by b2Distance.

int32 GetVertexCount ( ) const

inline

Get the vertex count.

void Set	(	const b2Shape *	shape,
		int32	index
	)

Initialize the proxy using the given shape. The shape must remain in scope while the proxy is in use.
