Hi mads,

> Is there a smooth function?

No, not currently - if you're looking for stuff like that it probably means you're trying to do a lot of surface control point manipulation. That means that you would probably be better off in a sub-d modeler that is focused on that kind of workflow, that kind of stuff is not a focus for MoI.

Probably in the future I will add some more stuff related to surface control point manipulation, but just in general it's a kind of restrictive thing with NURBS surfaces since NURBS surfaces are constrained in their topology to always have a rectangular net of points, that means that you can't add control point detail into one small local area of the surface, which is kind of why sub-d modeling is fundamentally better for that kind of point deformation type modeling approach.

In MoI you should generally be using a different modeling approach than that which is that kind of construction/drawing method that I mentioned above - that method tends to be a great fit for mechanical man made type objects but not so much for organic type shapes.

Hello Michael - that was a very helpful series of replies - thnaks

have been studying "magic" super posts on the FLOW tool - that is so unique that it could be a plugin for other appplication or even an app in itself.
have tried so many differnet wrap and projection workflows in other apps - but this one is so close to real life that only fluid dynamics can compare.
fascination!.
looking at the result from the speaker mesh - and another one he did with a mesh - ....

well - you might have x-ray'ed my workflow/app combination - and i appreciate your suggestion.
looking for the digital material with the power of nurbs and the freedom of subd.

something like the nurbs-cage-superstructure with subd/pixar surfaces grown with voxels. and all united as quads.

trying to find a digital workflow to add digital value skills to the traditional craftsmanship of the sculpturing artist - but that would be a long story

and always keeping the focus on the most important thing - an output into real word materials must be granted.

one important thing is also to load 20>40>60 million polygons from a high res details 3d scan - and still be able to run - chopping up the mesh is not always

i will follow along what is happening here.

would it not be an idea - for you or some of the others nurbs scientists to make a full featured flow, deformation, elastics and - there are parametrics, grasshopper around in various version - but they are not "intuitive"... and i would not consider them as a Tool to work with in daily 3d changing and various needs.
with elastics i am thinking about the way "glue" react when between two surface and you pull and turn these two surfaces apart. flow deformation as a reaction to the change of space between objects where the deformed solid can be adjusted by volume and different fall off.
to me it looks like a great niche on the marked next to fine things like moI3d.
or maybe i have not been through all the apps out there and it is already there.

or i am just day dreaming already before 10AM!

thank you so much
very much appreciated

best regards

Madsen,

Have you seen this? http://www.geometrysystems.net/default.htm

I have not tried it myself yet, but it's on my list to evaluate. There are numerous products out there that handle poly to nurbs conversion, but as far as I know, there is no app that will let you model in nurbs as "easily" as in polys.

T-Splines was definitely going in the right direction, although where its going know as part of Autodesk is unclear. The hope of T-Splines for me as well as others was that I could take a poly model and convert it to nurbs, and still easily modify it. However, the purpose of T-Splines, I keep reminding myself, is actually to creat a control mesh or low resolution proxy, to easily modify a nurbs object. It was never promised as a poly to nurbs converter simply because it is not designed to handle the sheer number of polys that are present in a detailed model or scan.

Geometry Systems is interesting because they seem to indicate the poly model, from a scan lets say, is tied to the nurbs model, so if you modify the polys, you also modify the nurbs. While superficially similar to T-Splines, they actually handle the full scan data. In theory this sounds great, but in actual use of the software, I don't know. I have to try it for myself.

Hi Chris - no - i have been crossing their homepage as i was looking for a 3d scan system - but have not look into their studio etc software.
will do - thx for the hint
cheers mads
