Utils.CrossProduct: Cross Product of two direction vectors in 3D space

In JerBoon/vecspace: Build a Hierarchy of Objects in 3D Euclidean (x,y,z) Space

Description

Cross Product of two direction vectors in 3D space

Usage

Utils.CrossProduct(a, b)

Arguments

a	First direction vector
b	Second direction vector

Value

Three element vector which is perpentical to the plane containing the two input vectors. Returns c(0,0,0) is the two inputs are parallel or if either are zero length.

Note: Utils.CrossProduct(a, b) == - Utils.CrossProduct(b, a)

This function is specifically coded for 3D space, i.e. totally expects both a and b to be 3 element vectors
