SYNOPSIS
       #include <volpack.h>

       vpResult
       vpSetVolumeSize(vpc, xlen, ylen, zlen)
           vpContext *vpc;
           int xlen, ylen, zlen;

ARGUMENTS
       vpc    VolPack context from vpCreateContext.

       xlen   Size of first dimension of the volume in voxels.

       ylen   Size of the second dimension of the volume in voxels.

       zlen   Size of the third dimension of the volume in voxels.

DESCRIPTION
       vpSetVolumeSize is used to define the dimensions of a volume.  It must
       be called before volume data is loaded into a rendering context.  Any
       existing precomputed volume data structures in the context are
       destroyed.

STATE VARIABLES
       The current volume dimensions may be retrieved with the following state
       variable codes (see vpGeti(3)): VP_XLEN, VP_YLEN, VP_ZLEN.

ERRORS
       The return value is always VP_OK.
