...with Jaimes save/load radiosity and lights while modelling some objects
for my IRTC scene.
Great work on those files Jaime. Thank you!
The razor is a wings3d model I did, the rest is csg. All procedural
textures.
I think there is artifacts below the cup because I used a 320x240 noAA
render to collect radiosity for the scene, and rendered the final image in
1280x1024. Is it because the aspect ratio doesn't match, or is it because
the resolution used to gather radiosity image is too small? I'm doing a
640x480 save radiosity scene now, which I will render in 1280x960 (who made
it 1280x1024 anyway? doesn't fit the 1.33/1 ratio..)

Hope you like!

-Peter

Nice modelling on the razor :)

Hi Peter:

  Very nice image! Seems a bit whased out on my screen, but the overall
ambient is great.

  I keep seing these amazing models done with Wings3d... I must try to
investigate why it doesn't compiles on my system: seems worth another
try to see if I can manage a GUI-modeller (;)).

  Yes, the problem is mainly the low resolution, I think. Each scene
seems to need a minum size to avoid these "line artifacts". In fact,
some still show them using the same resolution on the saving pass. You
can get ride of it raising a bit the error_bound for the load pass, but
this also introduces another "softer" artifacts. The ratio can be also
an issue, but doesn't seem to be the main problem.

  Yes!

Great image but the soap brush looks too solid on the bristle part.

As I've never used one of these old types, I couldn't figure out how it
worked from just looking at the reference pictures, so I had my da help me a
bit. It was easier to model it in Wings because he could see the changes
straight away.

Thanks! Yeah.. I know :) It's only a cylinder and a sphere with a simple
texture. I tried to make it better, first by making a lot of small objects,
then by using media (which I haven't used much at all). But as I'm planning
to add it to a scene where it'd be pretty small, the way it is now fits
pretty good..
Any idea on what approach I could use to make it more realistic and less
solid? I might need it to look better even if I don't plan it ;)

Well.. my models aren't that great (I have a webpage update ready with a few
more models/renderings, jsut need to get the time do update..) But Wings3d
is awesome, my card (KyroII) doesn't support it 100% though, so it looks
pretty bad :/ but it works..
There are some .rpm packages available for linux, see the wings forum for
the links.
You need the erlang runtime thing too, but you probably knew that already..
I've never made it run on linux either, but I'm just learning it, and my
boss made me format my linux box to use it as a win2k server :-/ ah well..

Yeah.. it disappeared at 640x480 res. will it help if I use AA on the
gahtering image?
I'll try out error_bound, thanks for the tips.
Radiosity is fun :)

You might be able to fake the multiple objects look by using a texture 
transparent in spots, but having several cylinder+sphere objects each 
inside each other... Or just use a macro to make true cylinders :-)

Jaime, have you visited the Spiraloid Digital Sculpting Forum?
http://cube.phlatt.net/forums/spiraloid/
One moderator is Bay Raitt ( ...did Gollum ).  It treats "digital 
sculpting" as an artform in itself.  There seems to be a strong 
predisposition to extend the traditions of figurative art into 3D 
character art, with a appreciation for anatomical accuracy.  It mostly 
involves polygonal mesh modelling and the astonishing organic effects 
that can be achieved. The technique involves creating a faceted "cage" 
then "smoothing" or interpelating the vertices
to get an organic surface.  Wings3d, of course, offers a simple but 
powerful toolset to support this particular technique.  -Jim

  Yes, I think it was erlang the one wich didn't want to compile.

  My condolences..

  IMHO, no. And after all, the save/load trick purpuse was to avoid aa
and other "slow" features on the first pass.

  ...among other things. :)
