A distance proxy is used by the GJK algorithm. It encapsulates any shape.
| 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.
| 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.
