Here's some results from my latest experiments with
John VanSickle's "New Surface Subdivision Suite":

I'd like to point out that My April 2004 IRTC entry
has a pair of aliens that use the same subdivision
surfaces as well. Also, one of my two Jan 2004 entries
has a simple subdivided model as well.
These things get a whole lot easier to use when you
have a modeler (and the two models in the IRTC were made
using the modeler I've developed). Now that I've got
uv-mapping working right (I think :-) I might update the
look of the Greb, and make one or two more alien races.
Regards,
John

I just had a look at it. Nice !

"Programming" images is the way for me. - so I'll
see if I can find ways to use macros to generate
the vertices for the subdivisions.

I don't understand how one can do UV-mapping on
surfaces with arbitrary topology. - I'll have to
read your documentation more thoroughly.
Btw.: Is there a way to make "inner" edges as sharp
as outer edges ? (See attached image.) I have tried
to specify sharp values for such "inner" edges, but
they don't seem get sharp at all.
Please explain.

The on-line docs contain an error. A sharpness of -1 causes the
sharpness to be *on* for all levels of subdivision, and not off (as the
page erroneously states).

Ok. Then I must have understood it right, even if it
was written wrong.
I have tried to specify different sharpness values
"manually" for such "inner" edges, but I'm still not
able to get them sharp.

I would do some testing to reproduce this problem, but
right now both of my machines are hip deep in an IRTC
render.

Ok.
Then I'll investigate this further on my own, just to
make sure that I'm not doing anything wrong or mis-
understanding something.

I'm sorry.
The fault was all mine. I just found an insect in my code.
Now all is working as it should. (See attached image.)
