Filling gaps in triangle mesh models

[aiem]

Hi all, a new tool to fill gaps in triangle mesh models, especially in models obtained from scan data, is available: http://www.ae3d.ru

Thanks Alaexander, that looks interesting. Are you the author of the software?

@unknownuser said:

Currently it works with “.off” files only.

What type of file is a .off?

Hi, Jim! Yes, I am. Concerning the .off file format please look: http://www.geomview.org/docs/html/OFF.html

Hi all, since the tool had been released, I had got several questions concerning .off files. There are many freely distributed converters to this format (http://meshlab.sourceforge.net/), but many of them don’t store information about vertex normals, in other words, always produce files with header “OFF”. Taking this into account, new version 1.041 of the standalone utility has been released. It differs from version 1.40 only in interpretation of files with header “OFF”. Now it is considered that in such files vertex normals are implicitly defined by the triangle vertex order, in other words, it is assumed that the vertex order of each triangle correctly defines its “internal” and “external” sides (in the hypothetical case that a mesh breaks this assumption it should be normalized using a proper mesh processor). So, now files with header “OFF” can be used in cases, which require files with explicitly defined vertex normals (header “NOFF”) in version 1.04. See, please, also the correspondingly updated topic 2 of the manual (http://www.ae3d.ru/).

Alexander

Hi all, version 1.05 has been released. In this release a 64-bit version of the standalone utility is added. The main difference from the previous version is a more flexible and efficient implementation of the filtering step, that allows to repair meshes preserving sharp features. In general, the repairing becomes more robust and in some cases faster.

Hi all, problems with the release built on October 28 have been fixed. In case of a new bug found, please use the corresponding form on the download page or send me an email directly. My best, Alexander.

Seems magic! I have made some publicity of it around the 3D world
If I have good understandood that can works as "Stand alone" without Rhinoceros?

Yes, you are right. The standalone version hasn’t any dependence on Rhino. It can be used with any mesh editor that supports import/export meshes in “OFF” format. In fact, the both kind of the Completer's release are only quite thin wrappers on the same engine. But, the absence of its own editing possibilities causes, that using this tool you can’t manually designate model’s boundaries to preserve them during the repairing.
