Hello,

Just bought Quidam to import 3d people inside MOI and just discovering it was impossible (bad .3DM export).Could it be possible to make a good 3D export with Poser software to MOI ? How is it possible to import 3d people in MOI to design with 3d human references

Bye,

Pierre.

It's just that is "polygons" 3DM and not real nurbs 3dm !
So seems difficult to import polygons in moi!

Till today you will obtain just a structure and not a surface!

Maybe with something like Tsplines ?

Salut Pierre,

It's probably best to do a polygonal export of your final Moi model and then merge your population in your favorite polygon software afterward.

Otherwise you could import 2d vector silhouettes for reference in Moi.

Hi Pierre, most likely the Quidam 3DM export was only creating polygon mesh objects in their exported 3DM files.

3DM files can contain a lot of different kinds of things, like NURBS solids, NURBS curves, dimension annotations, spotlights, polygon mesh objects, etc... But MoI only reads and writes NURBS objects from 3DM files.

You can convert a polygon mesh object in OBJ format into a set of wireframe lines that can then be opened in MoI using the utility here:

http://moi3d.com/wiki/Resources#Obj23dmWireframe_converter

So to use that export from Quidam or Poser as an OBJ file, then run that utility to load the OBJ file and write out a 3DM file - that 3DM file will contain curves in it with one line for each edge in the polygon model data. That 3DM file can then be imported into MoI to get a wireframe of the mesh data.

thanks a lot Michael. I'm going to try it quickly.

Mickael,

It works very well thank you !!!!. I'm going to reduce polygon number to reduce wireframe export in Moi... As a "pipe designer" i thank you again to create pipe tool in a weekend for me 2 years ago !!
Bye,

Pierre.

Michael,

Just last question : Why don't you integrate the .obj/ importer in MOI. Why an independant add-on ? Could it be improved to decrease the frame weight directly?

Thanks again.

Pierre.

Hi Pierre,

> Why don't you integrate the .obj/ importer in MOI. Why
> an independant add-on ?

I'd be afraid that people would think that MoI supported polygon mesh data when it didn't really.

I'd probably get a lot of questions like "I tried to open an OBJ file, and it doesn't look the same as in my polygon modeling program, why it only made up line segments?" ...


> Could it be improved to decrease the frame weight directly?

I'm not sure what you mean actually - do you mean you would want it to not just load the data directly from the OBJ file but also modify it in some way like throwing out some of the polygons that were existing in the file?

- Michael

Hahahahaha... Did you mean, like "ANDY!"

Hello michael,

I think i should decrease polygons numbers from Quidam (not from the plugin) ....So it means i have to buy Quidam Studio.
Thanks.

Pierre.

Burr, feed ANDY will you! he looks a bit malnourished ;)

"""""Burr, feed ANDY will you!"""""""""""

Hahahaha! Danny.. Yeah, trying to get the facet reduction down enough so that the NURBS file would import into MoI was rough.. It seemed to always want to chip away at the "biceps" for some reason...lol

Anyway, it is a poor path.. Would be easier to just draw Andy in MoI really quick!!! :o The file you see there is 130 mb.

Hi Pierre, there are also some other kinds of programs that are focused on reducing polygon counts for mesh data - here's one: http://www.atangeo.com/

You could also just head on down to 3d Content Central and grab your self a freebie, just choose the STEP download option.

I've attached 'James' who's weighs in at a measly 1.73MB but looks well fed :)

Cheers

Hahahaha! Danny, I dont know how he stays well fed though... Poor James is merley a "Joined surface".. His crotch is a mess!!!!!!!! (Must have leaky gut syndrome)

I really love these conversions that you can find over at the central though.. I wish i had this software that can do the poly conversions like this.. I had talked to someone once that said they just did a model in Solidworks from scan data!!!! I wonder if MoI's "save to Point File" command would provide the proper type of input for this, to bypass having to do the "Geomagic" type route?...

Hi Burr,

When you say "proper input", which application are you talking about inputting the points into?

The Geomagic stuff handles big point clouds where the points are not ordered in any particular way - it does a lot of work to analyze all the points and organize them, fit surfaces to them, etc...

- Michael

Hi Michael,
I was refering to SolidWorks and the Scan data comment I made.. But I dont suppose I was really going to get a detailed response from that... That could be more from the SolidWorks forum.. (I dont even have SolidWorks to start testing it)

I guess the question would then be if the save to point file command gives a good input as a "point cloud?"

Hi Burr,

I would think so - but it does depend on what particular formats SolidWorks can read point clouds from.

The save to point file command makes a simple text file with each point as one line in the text file. So the thing to look for in SolidWorks would be if it can read point clouds from text files like that.

- Michael

Hi Burr, so I guess it looks like SolidWorks may not read points from a text file like that directly, but there is a SolidWorks plug-in that you can get that will do it, from here:
