Hi Paul,

The best place to start would be to look at the df3 demo files. With the
Windows MegaPoV version they come under the demos\df3 directory. The
'make_df3.pov' creates a .df3 file from a series of slices through a
texture, 'use_df3.pov' takes the created .df3 and uses it as a media
density pattern.

The standard POVRay help file describes the .df3 file format in the
'Density_File' section under 'Patterns'; it is a very simple format so
you should be able to convert your TEM data.

Hope this helps a little,
	Mike Andrews.
