GetSupport()

int32 b2DistanceProxy::GetSupport ( const b2Vec2 &  d ) const

inline

Get the supporting vertex index in the given direction.

Definition at line 137 of file b2_distance.h.

GetSupportVertex()

const b2Vec2 & b2DistanceProxy::GetSupportVertex ( const b2Vec2 &  d ) const

inline

Get the supporting vertex in the given direction.

Definition at line 154 of file b2_distance.h.

GetVertex()

const b2Vec2 & b2DistanceProxy::GetVertex ( int32  index ) const

inline

Get a vertex by index. Used by b2Distance.

Definition at line 131 of file b2_distance.h.

GetVertexCount()

int32 b2DistanceProxy::GetVertexCount ( ) const

inline

Get the vertex count.

Definition at line 126 of file b2_distance.h.

Set() [1/2]

void b2DistanceProxy::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.

Definition at line 32 of file b2_distance.cpp.

Set() [2/2]

void b2DistanceProxy::Set	(	const b2Vec2 *	vertices,
		int32	count,
		float	radius
	)

Initialize the proxy using a vertex cloud and radius. The vertices must remain in scope while the proxy is in use.
