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.
