Detailed Description
This engine takes as input a three dimensional floating-point vector and a transformation matrix. The vector is assumed to be a row vector.
The engine multiplies the vector by the matrix and returns the result in the output point . The output direction contains the result when the matrix multiplication assumes the vector is a direction, and therefore ignores the translation part of the matrix. The output normalDirection contains the normalized direction
