Hi Max,

I was looking forward to see your update!!
Your examples look great, but i'm unable to replicate them.

It seems that the script only works on a primitive cube or extruded rectangle for me.?
Any thing drawn with a polygon line or booleaned solid either gives the error "unsupported polygon type! (2)" or the object just disappears.

Hi Glenn
This script doesn't support n-gons. Use triangles and quads.

I know about object disappearing bug. I'll take care of it.

Subdiv beta 4 :)

Fixed some geometry bugs
Improved mesh load speed (about 10x)
Added support of polar triangles


Don't use any other types of triangles


Added handy feature: switch mode
If you use hotkey to run this script, put the same key combination as command parameter
Example: Key: Z Command: _Subdiv_beta4 Z
After that you can switch script on and off with Z key.

Hi Max,

Thanks a lot for the update.

I have some really hard time to import anything a little bit complex
Here's for example what I get :

1290 Geometry error, 1290 recovered.



I'm not sure if it's something wrong with the .obj loader I use (the one coming from http://moi3d.com/forum/index.php?webtag=MOI&msg=6674.68 ) and if there is
anything you can 'do' to improve the loader. Looks like the loader have some trouble to deal with extreme non planar quads.

I checked this model. There are many twisted non-planar quads in the obj. I'll think how to improve my importObj script for using it with such complex models.
The scripts works well with other complex models with non-planar quads .
for example:

Hi Max,
_Subdiv_beta4 don't work for me on V3 MACSOX
I put the command _Subdiv_beta4 with Tab key but the panel Subdivision don't stay visible.
i've tested with skull and elephant
but in Moi if I put a solid Box and run the command _Subdiv_beta4, it's OK.
I think it's a matter of Mac and Memory.
Thanks

Hi Max,

First thank you a lot for all the effort you did on this polygonal converter.
I have no idea of the complexity to write something like that, but I just want to point a general 'smoothing' problem with the method you are using. (and I'm not talking about surface continuity)

In the image :



A ) Max Sub-d : Low Quality
B ) Max Sub-d : High Quality
C ) Npower SubD-Nurbs.

My concern here is the wobble effect from the version B (Max Sub-d : High Quality).
This wobble effect is also visible on object silhouette. I know that I shouldn't compare your script to
a commercial 500$ product, but I'm wondering if it's something that might be improve in the future ?

In other words, while you manage to keep continuity between patches, it seems the side effect is an overall shape/silhouette deformation. It's something very obvious for polygonal surface subdivision people, used to see very smooth surface transition and ultra smooth overall silhouette. (catmull-clark)

Thanks.

Hi PaQ,

Thank you for this valuable information. I have some ideas how to improve quality.

Hi Max
any idea about my problem above ?
thanks.

I tried -ImportObj- with Lisa-head from C4D


















Tried to join all surfaces but obviously take too much time
Obj file is 4 Mb,if saved in 3dm is 231 Mb

Hi Mauro,

> I tried -ImportObj- with Lisa-head from C4D

That looks very dense - is it a several times subdivided result that is being exported? If so then you want to try exporting the base level control mesh rather than already subdivided geometry.

Ciao Michael
Lisa comes from C4D content browser,she's already subdivided

I joined small patches (much quicker) to few bigger patches and after all I joined all bigger patches into one solid. Much quicker than do it as one time consuming process (I used that for that bottle above). Maybe that helps.

Hi Mauro,

just in case you need to recover her... ;-)

>any idea about my problem above ?
Sorry, I don't have a mac. But it's very strange, it should work.

Max,
I've tested all the example in this thread (and more) and none are running.
I've a 2 x 2,8 GHz Quad-Core Intel Xeon Mac Pro and 6 Go ram.
The Subdivision panel displays a split second and disappears.
No other Mac user had this problem ? It's curious...
Thanks...

Hi, yes I am a mac user as well and when running the script I see a window flashing up on the left upper corner and that is it.

Maybe this will be resolved soon but anyway your work is awesome !!

For me the subd script works well with MoI 2.52 (have not updated yet to 3.0) under OSX 10.8.5 with my old iMac.

Stefan

Check beta1 or beta2. Does it work?

Beta 5.

Fixed bug with high valence vertices (>16-20)
Some surface tuning. Not perfect, but smoother than beta4.



b4 - red, b5 - green

Upd: Fixed tolerance bug, which may cause errors while importing very small models. Reuploaded.
