No sorry we can't find legal version of Amapi somewhere except if someone want to resell it
Version 6 was not make the conversion and not be more available at Polyloop

@PAQ you can send me anything you want by PM (with something like yousend it, mediafire etc )
but take objects with little number of polygons < 1 000 , not a Zbrush file, my computer is 10 years old! :)

Hello,

Perhaps here, but ~$1K.

Hi Frenchy,
I dont think it will do the same type of conversion you are seeing there with power-sub-d... It will do the ol'e "convert each poly to a planar NURBS patch" conversion.. The power sub-d and newer stuff actually does a "fitting process" that creates a whole, new smooth nurbs surface.

@ Burr
Yes for the simple conversion: each polygons will be a surface patch: so a planar face will be a planr nurbs surface

Not sure for the second method: there is a choice of the ranks of smooth

Better if your polygon model is only quads!
But works also with 3 facets or more than 4 facets: but you have less rank of smooth

I think the ability to create patch boundaries by material in Modo is a nice feature.
It allows some control of patch placement.

Image shows original converted face patch on right, rebuilt(simplified) curves in middle
and new patch (right) with some point pulling applied.

Here an example by Beta Amapi 8 that beta testers have (never released) I have not :(
Polys to nurbs

Top smooth Poly CatmullClark --> Nurbs
Bottom Nurbs (Yellow Brep nurbs limit) <-- Polygons

Hexagon 2.5 is there too and it is free.

I have no idea what features people need but maybe it will help with some of the importing and exporting issues people are having as well.

I have not played with it myself but the videos on youtube are pretty good WHEN you get the right clips of course. Some peeps post videos that are not that great with it.

Hexagon is a French very cool modeler made by the same Amapi team , very similar for polygon modeler part
But there is not function for transfom polygon mesh in nurbs!
You can see some tutorial videos here

Slime lines !

Yeah I've Hexagon as well. Played with it a long time ago. Perhaps I need to reinstall it again and play with it again.
I don't know how the modeling tools compare to C4D but it can't be much worse/old fashioned than C4D.

Peace,

Attached NURBS male for scale reference or what ever,
just don't sell it or I'll release the lawyer dogs. :p

I tried to simplify it as much as possible but it's still about
2.5 MB.

Enjoy



EDIT: Replaced previous file with an updated version.

Thanks Danperk, should come is handy.

So, how did you get this NURBS version from Hexagon? (If this is what you used)

You're welcome Mike. It's produced with Power SubD-NURBS.

(for some reason, I missed the first part of this thread...)

So, How does T-Splines and Power Sub-D NURBS compare and differ?

Could it be that aside from T-Spline's innovation with the ability to form joint intersections (start-points, tri-points), the "cage" modification is really an implementation of Sub-D? People may consider the novelty of T-Splines for its ability to act like a Sub-D platfrom, and may believe that it is only possible because of the T-intersection concept.

What this may mean is that people shouldn't be wishing for T-Splines (per se) in their NURBS application, but the ability to work an enclosed NURBS (water tight) solids by means of a Sub-D type cage system.

"Sub-D style cage", not to be confused with a "FFD deformation cage" that is on the MoI wish list. ;-)

None the less, T-Splines and Power NURBS products are pricey plug-ins for the non-commercial user.

Hi Mike,

> So, How does T-Splines and Power Sub-D NURBS compare and differ?

Well, one difference is that they are each plug-ins to different programs - T-Splines is a Rhino plug-in and Power Sub-D NURBS is a Modo plugin.

They both have conversion capabilities for converting a sub-d cage into a set of NURBS surfaces.

T-Splines also adds a variety of sub-d modeling tools to Rhino in addition to the conversion tool - I think Sub-D NURBS is only focused on the conversion part, Modo has a full set of sub-d modeling tools in it already unlike Rhino.

>>None the less, T-Splines and Power NURBS products are pricey plug-ins for the non-commercial user.<<

If the price of Power Sub-D NURBS was $300 - $400 range would have been more in line with my perceived
worth. ;) Probably still too pricey for non-commercial users, which pretty well describes CAD software in
general. (excluding MoI and a few others)

Ah... thanks.

And now with the new plug of Michael http://moi3d.com/download/Obj23dmWireframe.zip
you can make or take any polygons humans from any 3D prog (http://www.makehuman.org/ for free build your perfect hero! ;)
make some decimation http://meshlab.sourceforge.net/ and import it inside Moi!
No need Tspline or Subd surf ;)

And if you want a very free heavy complex model or a part of it (16 millions polys) so some decimation will be necessary!
Delete all the internal body! ;)

Hi PILOU


I guess by "make some decimation http://meshlab.sourceforge.net/" you can some how use meshlab to reduce the number of faces?

I've only used meshlabs to check for holes :)
