tripleProduct MethodStatic

Returns Returns the triple product of 3 vectors provided as x,y,z number sequences.

• The triple product is the determinant of the 3x3 matrix with the 9 numbers placed in either row or column order.
• The triple product is positive if the 3 vectors form a right handed coordinate system.
• The triple product is negative if the 3 vectors form a left handed coordinate system.
• Treating the 9 numbers as 3 vectors U, V, W, any of these formulas gives the same result:

** U dot (V cross W) ** V dot (W cross U) ** W dot (U cross V) ** (-U dot (W cross V)) -- (note the negative -- reversing cross product order changes the sign) ** (-V dot (U cross W)) -- (note the negative -- reversing cross product order changes the sign) ** (-W dot (V cross U)) -- (note the negative -- reversing cross product order changes the sign)

• the triple product is 6 times the (signed) volume of the tetrahedron with the three vectors as edges from a common vertex.
