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
INPUTS
SoMFVec3f vector
Input row vector.
SoMFMatrix matrix
Input transformation matrix.
OUTPUTS
(SoMFVec3f) point
Vector transformed by matrix.
(SoMFVec3f) direction
Vector transformed by matrix, ignoring translation.
(SoMFVec3f) normalDirection
Normalized direction.
