Function ncollide3d::utils::tetrahedron_signed_volume [−][src]
pub fn tetrahedron_signed_volume<N: RealField>(
p1: &Point<N>,
p2: &Point<N>,
p3: &Point<N>,
p4: &Point<N>
) -> N
Computes the signed volume of a tetrahedron.
If it is positive, p4 is on the half-space pointed by the normal of the oriented triangle
(p1, p2, p3).
