	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:
