Functions
template<typename Vec3T>
__hostdev__ Vec3T	closestPointOnSegmentToPoint (const Vec3T &v0, const Vec3T &v1, const Vec3T &p)
	Returns the closest point on the line segment [v0,v1] to p.
template<typename Vec3T>
__hostdev__ Vec3T	closestPointOnTriangleToPoint (const Vec3T &v0, const Vec3T &v1, const Vec3T &v2, const Vec3T &p, typename Vec3T::ValueType &t0, typename Vec3T::ValueType &t1)
	Returns the closest point on triangle [v0,v1,v2] to p, and (via t0, t1) the barycentric coordinates of that point: closest = v0 + t0*(v1-v0) + t1*(v2-v0).
template<typename Vec3T>
__hostdev__ Vec3T::ValueType	pointToTriangleDistSqr (const Vec3T &v0, const Vec3T &v1, const Vec3T &v2, const Vec3T &p)
	Returns the squared distance from p to the closest point on triangle [v0,v1,v2].
