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.
