getc3 |
                 getc3(i, m3, chunk)
              or getc3(i, m3, clist, l, u, fsl, fsu, cells)

         return cell values of the Ith function attached to 3D mesh M3
         for cells in the specified CHUNK.  The CHUNK may be a list of
         cell indices, in which case getc3 returns a (dimsof(CHUNK))
         list of vertex coordinates.  CHUNK may also be a mesh-specific data
         structure used in the slice3 routine, in which case getc3 may
         return a (ni)x(nj)x(nk) array of vertex values.  There is no
         savings in the amount of data for such a CHUNK, but the gather
         operation is cheaper than a general list of cell indices.
         Use getc3 when writing colorng functions for slice3.
         If CHUNK is a CLIST, the additional arguments L, U, FSL, and FSU
         are vertex index lists which override the CLIST if the Ith attached
         function is defined on mesh vertices.  L and U are index lists into
         the 2x2x2x(dimsof(CLIST)) vertex value array, say vva, and FSL
         and FSU are corresponding interpolation coefficients; the zone
         centered value is computed as a weighted average of involving these
         coefficients.  The CELLS argument is required by histogram to do
         the averaging.  See the source code for details.
         By default, this conversion (if necessary) is done by averaging
         the eight vertex-centered values.

getv3 |
                 getv3(i, m3, chunk)

         return vertex values of the Ith function attached to 3D mesh M3
         for cells in the specified CHUNK.  The CHUNK may be a list of
         cell indices, in which case getv3 returns a 2x2x2x(dimsof(CHUNK))
         list of vertex coordinates.  CHUNK may also be a mesh-specific data
         structure used in the slice3 routine, in which case getv3 may
         return a (ni)x(nj)x(nk) array of vertex values.  For meshes which
         are logically rectangular or consist of several rectangular
         patches, this is up to 8 times less data, with a concomitant
         performance advantage.  Use getv3 when writing slicing functions
         for slice3.
