Elevation Shading in Object Graphics [message #13351]

Hi Folks,

Well, naturally, I hadn't posted my "Elevation Shading in
Object Graphics" example on my web page for more than 10
minutes when people more knowledgeable than I starting
pointing out the obvious faults.

In particular (and it is exceedingly odd that neither I
nor the folks who were helping me at RSI noticed this) it
is a LOT better to turn shading ON, although it is still
true that you want to have lights OFF.

I also discovered that it is better to add a color palette
to the surface (thanks to Struan) than to the window, which
I was doing previously. (Actually, it works the same, it
just seems more natural and elegant to add it to the
surface, where it really belongs.)

Anyway, I think I have it sorted out now and you can view
the article and code at these URLs:

As always, a big thanks to the anonymous lurkers who
keep me on the straight and narrow. :-)

Cheers,

David
