My own little "addition" to this is that the routine in GSAS (POLFPLOT) for
plotting of pole figures from spherical harmonics texture coefficients now
has an option to create a VRML file showing a 3D view of the pole
distribution. It's useful for visualizing the texture even for "ordinary"
x-ray Rietveld refinements.
