After reading several entries in the news list concerning ISOSURFACE,
SHADE_VOLUME, INTERVAL_VOLUME, MESH_... I am still a bit confused.
Look at the attached piece of code, where a 15^3 volume containing a 3^3
cube of value 100 is displayed using the mentioned idl routines with
different values/isovalues/thresholds.
ISOSURFACE is dispayed at Z=0, SHADE_VOLUME at z=-4 and INTERVAL_VOLUME at
z=+4. Beside the strange volumes calculated, I had expected nearly
simmilar results, ISOSURFACE does not follow SHADE_VOLUME as described in
the help, in fact it is seemingly using INTERVAL_VOLUME, at least
partially.
Maybe there are some experts to explain this behaviour.
However I have the impression that the graphics folks seem to have still a
long way to find a common language.
Any help is appreciated
