NAME¶
vpMultMatrix - multiply the current transformation matrix by another matrixSYNOPSIS¶
#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.SEE ALSO¶
