afaik, sombody is already working on this. Madprof is away for a month
tho.....along with new effects he's also working on these kinds of
non-destructive operations.

  Hi, I've got  sort of feature request to compliment the new radiosity
system and make it easier to use. Maybe someone has a better idea how to
solve the problem too! ....and more important the time and knowledge to
impliment it! :o/



  WHAT:
  Would it be possible for someone to impliment a rigid sub-surf system?
Like the catmul clark sub-surfs but which doesn't distort the mesh. In other
words:  a cube remains a cube!

  WHY:
  To compliment and facilitate the use of the new animatable radiosity sytem
implimented by Ton.

  THE PROBLEM:
  The new radiosity system does not currently subdivide the mesh but works
with the available mesh. This is not a problem with organic meshes which
have sub-surfaces - but for 'rigid', non organic shapes like buildings,
furniture etc the user has to sub-divide the mesh manually before rendering.
This increases polygon count unnessesarily and makes editing harder after.

  So a sub-surface system which leaves the mesh as-is would be great!
Especially with Goofsters new loop cut tool, it is possible to easily
control the density of such a subsurface to specific places, while only
increasing the face count of the non sub-surf mesh minimally!

  WHERE:
  I would put it as a toggle button next to the current Sub-surf buttons in
the edit buttons. So the user switches on Sub-surf normally but then toggles
between Catmul-clark (current) and the non-smoothing system (proposed). You
wouldn't need both at the same time after all! :o)

  Eventually it could be moved to the effects buttons, though I don't see
any use for such a sub-surface except in conjunction with the new radiosity
system as it currently is.




  So anybody else think this is necessary and useful? If yes, could it be
done before 2.29 is released with the new radiosity system?


  Thanks!

  Regards
  Fabrizio
