I am awfully sorry. I never wanted to put words in your mouth.

I must say I was surprised to find my post a bit harsh when I re-read it
today. I wasn't my intention at all.

All in all, what I wanted to say is that I was a little disappointed that
the old bumps was accessible only through #version, because I thought that
it still has uses in current megapov (future pov?) versions. But as it seems
it is easy to make it work in povscript , all is well.

Great. I suppose the corrected-map solution would be the quickest
(render-time-wise). For the function pattern, I suppose you mean wrapping an
"adapter" function around the noise/bumps.

Just for interest's sake: is it possible to re-write the old noise/bumps
function from scratch in povscript? Isn't the noise function iterative? Is
it possible to write iterative functions for the function pattern or
isosurface?


Thank you for your explanations (I _like_ the TAG team),


Povingly,


Philippe
