Member Function Documentation

bind()

static void hpp::fcl::details::EPA::bind ( SimplexF *  fa, size_t  ea, SimplexF *  fb, size_t  eb  )

inlinestatic

evaluate()

Status hpp::fcl::details::EPA::evaluate	(	GJK &	gjk,
		const Vec3f &	guess
	)

Returns

a Status which can be demangled using (status & Valid) or (status & Failed). The other values provide a more detailled status

getClosestPoints()

bool hpp::fcl::details::EPA::getClosestPoints	(	const MinkowskiDiff &	shape,
		Vec3f &	w0,
		Vec3f &	w1
	)

Get the closest points on each object.

Returns

true on success
