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.
Ben

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?

hello,
I made a new primitive for gem : curve3D.... juste like curve, but in 3D!
you may find stuff here :

picts, source, exemple and gem.dll for windows user...
hope you'll like it...

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.

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?
a 3-3 control point cube made up of "curves" as an abstraction is getting to be a little anoying!
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"?

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.

ok.

yes, it's possible with the curent version of curve3D to do enclosed shape. for a 5 5 control matrix of the curve3D object if : control[0][i]=0,0 control[4][i]=0,0 control[i][0]=0,0 control[i][4]=0,0
the curve will then be an enclosed shape. (0,0 will be part of the curve) the shape will depend of the other control points.
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.
a sphere can also be done with the curve3D object using this :
with the 5 5 control matrix : control[0][i] = circle diamettre = 0, heigh = 0 control[1][i] = circle diamettre = 0.7, heigh = 0.3 control[2][i] = circle diamettre = 1, heigh = 0.5 control[3][i] = circle diamettre = 0.7, heigh = 0.8 control[4][i] = circle diamettre = 0, heigh = 1
(it's possible with 5 points to draw a circle) value are only aproximations exact value can be found on internet...
I may not be very clear???
and yes, hard angles can be done using more than 1 curve3d, but I don't know how to assume that all angle will alway be 90°.
I'm CCing on the gem-dev so perhaps someone with better french can explain what I'm talking about.
I hope I understant this time.
I like the idee of the blob or other enclosed shape but I don't know (understand) how to control it in a better way than what's is curently possible... any idee of what I'm missing?
I made a patch of enclosed shape with curve3d : you may find pict (new_tentacle) here :
http://drpichon.free.fr/pure-data/GEM/curve3D/

Thanks for the good work.
