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.
