# fz_math_3d_volume_of_tetrahedron

Description

Calculates the volume of a tetrahedron. The tetrahedron is defined by four points. p1, p2 and p3 form the base triangle and top is the tip. A negative volume is returned if the top of the tetrahedron is on the negative side (right hand rule) of the base triangle formed by p1,p2 and p3.
