Use \fBvpCurrentMatrix\fR to set the current transformation matrix. .SH "STATE VARIABLES" The current transformation matrix parameters can be retrieved with the following state variable codes (see vpGeti(3)): VP_CURRENT_MATRIX. .SH ERRORS The return value is always VP_OK. .SH SEE ALSO VolPack(3), vpCreateContext(3), vpCurrentMatrix(3), vpGetMatrix(3)
