vpGetMatrix - retrieve the contents of a transformation matrix

vpc    VolPack context from vpCreateContext.matrix_code
              A  code  specifying  one  of the VolPack transformation matrices (VP_MODEL, VP_VIEW, VP_PROJECT or
              VP_SCREEN).

       matrix Matrix for storing the result.

vpGetMatrix retrieves the contents of one of the transformation matrices (see  vpCurrentMatrix(3)).   The
       special code VP_SCREEN causes the function to compute the transformation from object coordinates to image
       coordinates and return a matrix describing this transformation.

       The normal return value is VP_OK.  The following error return value is possible:

       VPERROR_BAD_OPTION
              The matrix_code argument is invalid.
