vpMultMatrix: multiply the current transformation matrix by another
Command to display vpMultMatrix
manual in Linux: $ man 3 vpMultMatrix
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.
