	)		const

Return potential intersection with face with a ray starting at p, direction n (does not need to be normalized)

Does face-centre decomposition and returns triangle intersection point closest to p. Face-centre is calculated from point average. For a hit, the distance is signed. Positive number represents the point in front of triangle In case of miss the point is the nearest point on the face and the distance is the distance between the intersection point and the original point. The half-ray or full-ray intersection and the contact sphere adjustment of the projection vector is set by the intersection parameters
