vpMultMatrix(3) Library Functions Manual vpMultMatrix(3) 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 vpMultMa- trix). The VP_CONCAT_MODE option to vpSeti can be used to select pre-mul- tiplication. STATE VARIABLES The current matrix concatenation parameters can be retrieved with the fol- lowing state variable codes (see vpGeti(3)): VP_CURRENT_MATRIX, VP_CON- CAT_MODE. ERRORS The return value is always VP_OK. SEE ALSO VolPack(3), vpCreateContext(3), vpCurrentMatrix(3) VolPack vpMultMatrix(3)
