Yes for sure,
I've mentioned this to Chris before and its something that would be really great for Gem. (Perhaps just a set of good NURBS-like controllable surfaces would be a good start...) Are Gem textures "projected" onto geometry are are they mapped to the UV coords?
they are maped to the UV coords for curve3d.
a 3-3 control point cube made up of "curves" as an abstraction is getting to be a little anoying!
well, 27 control points. how to do the same things with another way?
Oh and curve3D should be renamed to curve3d to match the Gem convention (ie text3d) you could also call it "open-surface" compared to a possible "closed-surface"?
ok for curve3d. I made the change on my local directory.

I have not yet been able to try the new externals, but I'd like to share a thought about geometric objects that I had, and that is the implementation of NURBS objects. I think this could make manipulations possible that have been hard to implement up to now in GEM.

Hi Cyrille,
What I'm making right now as an abstraction made out of 6 of your curve surfaces, each representing a face of a cube. Of course thic cube can be deformed to become a curve, but the edges between faces will always be
90
degrees. (hard edge)
So is there the possibility of having an enclosed shape (like the cube example above, where there is an intererior and an exterior that are non-continuous. A torus, cone, sphere, cube are all enclosed. A plane,
your
curve, and circle are not enclosed because they have only one surface
(no
interior).
A blob would be different than the above example because it would not
have
any hard edges. A bubble is a blob... Basically I'm asking for a sphere primitive that you can move control points to destort the surface.
I'm CCing on the gem-dev so perhaps someone with better french can
explain
what I'm talking about.
Thanks for the good work.

Hello Ben,
I'm not sure to understand everything. (still nead to progresse in english.) google does not have a good translation...
what's an "enclosed curvy shape"?
what's a blob?

Hey Cyrille,
I'm just patching up an abstraction for an enclosed curvy shape. But
as I
mess around I realize it would make much more sense as an external.
Are
there any plans for an enclosed version of curve3d? (which would be basically like a blob) I'd really like this...
thank's
Thanks again for the good work.
well, I just copy my open GL book!

hello,
I made a new primitive for gem : curve3D.... juste like curve, but in 3D!
you may find stuff here :
http://drpichon.free.fr/pure-data/GEM/curve3D/
picts, source, exemple and gem.dll for windows user...
hope you'll like it...
