Hi everyone, I wanted to do a conversion test in NURBS surfaces this 3D scan(https://www.thingiverse.com/thing:1415162), I used Blender to generate the square topology with the remesh modifier, then I exported to OBJ and I created a new mesh using a free app Instant_Mesh to generate a smaller file 21.9MB (21.882.962 bytes), finally I imported in Moi3D to generate the NURBS surface from the square mesh obj model, the conversion was successful but the resulting file is huge, unmanageable, to be used too heavy 1.6GB (1.564.648.052 byte)

Below the zip file contain the file use for the NURBS conversion.

Hi pafurijaz, thanks for testing it! It is not really expected that such a highly detailed and heavy mesh would give a manageable result, it would need to be significantly simplified for that.

The main focus of the converter is to give a highly accurate result, it's really more intended to enable getting a smooth and accurate conversion from a light sub-d cage so that can be used as a base shape for further NURBS modeling.

Conversion of 3D scanned data really needs a more specialized tool that is focused entirely on that process, it is not a specific focus area of MoI's converter.

That being said it is good to see some "torture testing" of it as well!

I make the same with your file (used Zbrush Decimation Master 10% - gives me a file OBJ 1 .5 megas )

But subdiv in Moi gives a 3dm quasi 1 Giga ! (980 megas) not manageable on my Latop! (just following)
https://www.filehosting.org/file/details/790793/Rhino_scan_remk.zip (file 3dm of 980 megas)


with Decimation Master 5 % gives a file OBJ 660 KB for a 3dm of 450 Megas!
https://www.filehosting.org/file/details/790794/Rhino_scan_remk660.zip (file 3dm of 450 megas)
More easy! Just following!

Even with a very big decimation (0,5 %)

(unzip = .3dm of 44 megas for an .obj of 660 KB)

Boolean Operation takes some times! A Boolean Diff with a Simple Sphere takes 20 sec! ;)
Does it the same for you ?

Even with a big decimation here in Zbrush Decimation Master (0.5 % )



Operations after importation by subdivision take some times! :)

Boolean Diff a simple sphere takes 20 seconds!

And Rhino is something like a Pompom's sculpture! :)

Hi Pilou,

try Instant Meshes! (https://igl.ethz.ch/projects/instant-meshes/)

I exported an obj of around 8K polygons, pure quad mesh with a file size of 3.5MB. Imported nicely into Moi3D.

3dm file was around 88MB but it looks clean and i can boolean diff a sphere in 10-15 sec on my MBP :-)

Playing with different polygon counts is easy in Instant Meshes so give it a go!

Dinos

I took your OBJ file and run it inside Zbrush for decimate it! ;)

And I suppose the Zbrush Decimaster has same functions than Instant Mesher! ;)

It's more that problem : I have only 8 Gigas ram on my Latop!

And seems I have same time consuming for boolean function than you! ;)

Ps Have you a direct link for download an Instant Mesher windows version ? Because I am a little losted over all these files!
(without line command if possible! :)

Else 8 years old! ;)

Sure, you can download it from the github page: https://github.com/wjakob/instant-meshes

Its fast and efficient and should run nicely on your computer.
It even has a really nice UI to play with :-)

Hi Pilou,

re:

> Does it the same for you ?

This is probably because of the relatively high face count in the model. Your model appears to be made up of all triangles instead of being a quad-dominant mesh set up for sub-d smoothing. So because of that you're getting a lot of little tiny faces.

The sub-d importer is primarily focused on converting sub-d models, not non-sub-d triangle mesh models like you are using there.

Thx but the direct link for Windows all in one Standalone was a little more following! ;)

After some clicking I finally found it! :)

Probably been asked before tried to search but couldn't dig anything up - is there a way to set BROWSER - Object / Types / Styles to be rolled out permanently on starting a new doc - find its a repetitive function that I do with new docs in MOI.

Hi Alex, it is possible in v4 to have scene browser items expanded on program launch by making a startup script as described here:

thanks Michael works great.

Hi Michael, any very rough timeline on the next beta release? I hate to be that guy, but I would love to have something exciting to look forward to :)

Hi nameless, re: next beta release - well I'm heading out on vacation for a week. Maybe something like 3 weeks from now?

I've been making progress on basic dimension annotations but it still needs some more work.

- Michael

Hi Michael,

I wish you fun and relaxation in your vacation! And looking forward to it :)

Out of curiousity, I've been checking the contents of a few folders. :-)

In the MoI4.0_Beta_Feb-26-2019, commands folder, I have 267 "stock" command related files, (<50% .htm, and> 50% .js).

In the %AppData" / Moi/Commands folder, I have 1089 files. There are 266 "stock" command related files (more or less duplicates of the MoI4.0_Beta commands folder (-1)).
(I thought that the "stock" commands were supposed to be in the beta/commands folder, but at present they are in both locations.)

There are 823 additional "add-on" files, with _underline prefix, (<50% .htm), including quite a few experimental commands, and "mod" versions.

So one question is, in which directory do the "stock" MoI commands belong? Did the last update put the "stock" commands in the %AppData% Commands subdirectory?

- Brian

Hi Brian, MoI shouldn't have put any commands at all in the appdata commands folder, all those would have gotten there from you copying them in there.

It's intended that the stock commands are not in appdata, they are intended to be in the old install directory commands folder. That's so that if any of them are updated with some new features you will get them along with the new install.

When you run a command and the same command is present in both the install commands dir and the appdata commands dir, the install one will take precedence.

So it doesn't do any actual harm to have them additionally in the appdata dir though.

Hope that's what you were asking about!

Feature Request - I've been using MOI for 3d printing and it is awesome and does great exports to STL files. Would it be possible for MOI to be able to import STL files so that we could support the entire life-cycle of 3d printing?

Imagine being able to download ANY file off of Thingverse and modify it and print it....it would be a great boost for my workflow. I can really see MOI being able to excel in that niche.

I understand if it's not possible but I love MOI and figured it wouldn't hurt to ask. :-)

Best, Nicholas

Hi Nicholas,
I'll go along with your wish. There are a large number of models at Thingivers that can be used with minor changes. Unfortunately not every 3D program can process the STL files.
I myself have published a lot of STL files of models (of course constructed with MoI ;-)) there.
Greetings
