vpSetVolumeSize - define the dimensions of a volume

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.

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.

       The return value is always VP_OK.

VolPack                                                                                       vpSetVolumeSize(3)

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

       #include <volpack.h>

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