NAME

       vpMultMatrix  -  multiply  the current transformation matrix by another
       matrix

SYNOPSIS

       #include <volpack.h>

       vpResult
       vpMultMatrix(vpc, m)
           vpContext *vpc;
           vpMatrix4 m;

ARGUMENTS

       vpc    VolPack context from vpCreateContext.

       m      Input matrix.

DESCRIPTION

       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.

STATE VARIABLES

       The  current  matrix concatenation parameters can be retrieved with the
       following state  variable  codes  (see  vpGeti(3)):  VP_CURRENT_MATRIX,
       VP_CONCAT_MODE.

ERRORS

       The return value is always VP_OK.
