Hello,

I have tried using graver to convert my logo to a relief, with
 success. However, I would like a smooth relief, rather than
 the sharp-relief obtained from using graver with convex
 setting.

What I want is something likened to embossing, or a
 'melted-wax' type raised effect.

Could I achieve this by simply scaling the height of the
 graver output logarythmically? How - just by putting
 a logarythmic expression in a 'scale' vector?

Alternatively, is there a utility which will give me the
 result I am after?

Simeon
PS what happened to the very-useul povray.org
 utitlity library? It seems to exist only in
 almost-completely-useless ftp format!

Not sure what details you like, but in povray you'd need a png/tga/gif
of the logo and then do this...with a different texture and finish (to
get it smooth)....
