DESCRIPTION

69       This engine takes as input a three  dimensional  floating-point  vector
70       and a transformation matrix. The vector is assumed to be a row vector.
71
72       The  engine  multiplies the vector by the matrix and returns the result
73       in the output point. The output direction contains the result when  the
74       matrix  multiplication assumes the vector is a direction, and therefore
75       ignores the translation part of the matrix. The output  normalDirection
76       contains the normalized direction
77

83          Input transformation matrix.
