Purpose

The engine SoTransformVec3f 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, thereby ignoring the translation part of the matrix. The output Normal Direction contains the normalized direction.
