MeshLab is an open, portable, extensible system for the user-assisted processing of unstructured 3D meshes. The system is aimed to help the processing of 3D models arising in 3D scanning, providing a set of tools for cleaning and healing this kind of meshes.
Thread Rating:- 1.2.2 Replath; 1.3 Closed source. A Mac native preview has been unveiled and is planned to be available early 2012. An open source, portable.
- I updated my gcc from 4.2.1 to the latest 4.9.2 (for another reason) and now my obj model works in CC just as well as it works with meshlab. I also use jpg instead of png images. In my obj file is 12 materials, 24 points and 4 tex.coord. My CloudCompare version is 2.5.5 Mac OS 64 bits and I use 10.9.5 macbook(-08).

Share Thread:Wings 3D crashes upon importing, exporting complex .obj, model. |

| Wings 3D crashes upon importing, exporting complex .obj, model. Hello, everyone. Thank you for providing this wonderful piece of software for free. However, I'd like to report a bug. I think the issue might have to do with file sizes but I'm not sure. Trying to import the following .obj model into Wings 3D to autosmooth then export back, overwriting the original file, Wings 3D crashes. Importing the following file : https://drive.google.com/open?id=0BwJaCs...3dJYWdNdmM Applying autosmooth with a crease angle of 15 degrees then trying to export the file overwriting the original file imported into Wings 3D, Wings 3D crashes. An incomplete, invalid .obj file is created which is a few bytes or KB in size. The .obj model is a rather detailed .obj model. It is fully triangulated and obtained by converting an .stl file to .obj using Meshlab (and choosing to unify duplicate vertices upon importing the .stl file into Meshlab, before exporting it from Meshlab as an .obj). I also apply the 're-orient all faces coherently' filter in Meshlab on the mesh imported from the .stl file, after merging duplicate vertices upon import and before exporting the model as an .obj. Wings 3D does not crash with a simpler version of the same model and exports it successfully after applying auto-smoothing with a crease angle of 15 degrees. Here's what that exported file looks like (animated png so it can only be viewed using Firefox and Safari) : https://drive.google.com/open?id=0BwJaCs...jduUU83R3M Note that trying to apply subdivision or smoothing even to that version of the model likewise causes Wings 3D to crash but that's likely a different bug. Or maybe normal when trying to apply smoothing or subdivision on a fully triangulated, hi-def mesh? Also, with an even more complex version of the same model than what causes it to crash on export it actually crashes trying to import the file. If needed I can provide that more complex version of the model as well. A.

Ivcon | License: unknown Debian package not available |
IVCon is an executable C++ program that can read and write a varietyof 3D graphics file formats, converting from one to the other. This is extended version of John Burkardt's great, but buggy tool.It Supports many 3D formats, and a lot of 3D scene elements. Supported formats include 3DS, ASE, BYU, DXF, GMOD, HRC, IV, OBJ, OFF,POV, SMF, STL/STLA/STLB, TEC, TRI/TRIA/TRIB, UCD, VLA, WRL/VRML, XGLand more. The program supports many elements of 3D scene, but specific convertersmay not support all of them. There are two possible reasons of that: oneis that the support is not fully programmed inside this tool, second isthat the format may not have possibilities to support the item. Goodexample is the ASC format - which is an ASCII cloud of vertices, andsupports only bare points in 3D space. | |
