xyz3(m3, chunk)
return vertex coordinates for CHUNK of 3D mesh M3. The CHUNK
may be a list of cell indices, in which case xyz3 returns a
3x2x2x2x(dimsof(CHUNK)) list of vertex coordinates. CHUNK may
also be a mesh-specific data structure used in the slice3
routine, in which case xyz3 may return a 3x(ni)x(nj)x(nk)
array of vertex coordinates. 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 xyz3 when writing slicing functions or coloring
functions for slice3.
