Crayons - Real3Dv2 scene (01.8.94)

*****************************************************************************
Having seen StudioPro's demonstration picture - "Crayons", which
features soft shadows and color bleeding thanks to RAYDIOSITY (TM) method,
and then raytraced picture done with the same package, included clearly to
show that raytracing is inferior to this new technique, I started to wonder
if it is possible to recreate the thing with one of Amiga modelling and
animation packages. My choice was Real3Dv2, mostly due to its excellent,
photographics quality output and distributed raytracing, giving me the way
to imitate radiosity's soft shadows.
Modeling was done during two days and anyone who knows Real
modelling abilities will certainly agree that I didn't push it to its
limits. Setting proper lightning took me one more day, due to really slow
rendering when soft shadows are on. Realism (and rendering time :-)) of
the scene was further enhanced with depth of field effect.
Final picture was rendered with antialiasing set to 3 and
lightsamples to 6, what at resolution 728x582 amounts to 41 hours on my
10MB A4000/040. And if you think it's slow, you should see RAYDIOSITY (TM)
at work. Enough to say that we never had a patience to complete rendering
- and don't forget that Emplant on A4000 is in fact faster than Mac with
the same processor (did you really think that we had used original Mac to
run StudioPro ? :-)).
Anyway, Real's picture looks (IMHO) much better than StudioPro's
raytraced one, although probably not as good as that generated with
RAYDIOSITY(TM). I guess I would need second area light, and more careful
modelling of table's (or whatever it is) surface.
Right, in this package you will find project file, textures and
rendered picture (in JPEG format). One thing that's missing is
environmental map (took out to reduce archive size), but it can be any
(best if colorful) picture from your collection. If you are short on
memory, try decreasing a lightsamples value.
If you want to send me some R3D2 objects or just to have a chat
about computer graphics (especially image synthesis), please contact me:
