- Input matrix.
vpMultMatrix is used to multiply the current transformation matrix by an
arbitrary 4-by-4 transformation matrix. Use
vpCurrentMatrix to set the
current transformation matrix. By default, the matrix is post-multiplied (N =
N*
m where N is the current matrix and
m is the argument to
vpMultMatrix). The VP_CONCAT_MODE option to
vpSeti can be used
to select pre-multiplication.
The current matrix concatenation parameters can be retrieved with the following
state variable codes (see vpGeti(3)): VP_CURRENT_MATRIX, VP_CONCAT_MODE.
The return value is always VP_OK.
