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.
