Hi Micha, I do think that the kind of "max error" (possibly I will call it Chord height) should get added in as a new meshing parameter in v3.

Currently you would probably want to use "Divide larger than" to force some additional divisions in larger slightly curved objects like you show there - that's probably a bit easier than using a tight angle + "Avoid smaller than" which it sounds like you are doing now.

One of the things that I want to figure out is some way to have that kind of chord height switchable between 2 modes - a "percent relative to the bounding box size" mode, and an "absolute distance value" mode.

It would be helpful for the default simple dialog (where only the slider is showing) to also set this value in the relative size mode when moving the slider around instead of only the angle parameter alone.

I'm not a fan of "divide larger than" since it divide not only in curved directions. So I get much to much polygons - see screenshot. If it would work perfect, it would devide in the curved direction only. This you could implement without to change any UI. ;)

Hi Micha, I see - but "divide larger than" would work without complication on that previous example that you posted though.

I also have that on my list as well, to make "Divide larger than" when set to apply to curved surfaces only to not divide in the straight direction on extruded surfaces.

Great, thank you.

I've been able to cook up the "merge obj files" utility that was mentioned earlier in this thread, it's available here:

http://moi3d.com/download/MergeOBJ.exe

And I updated the wiki resources page to list it:

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


So hopefully that should do the trick if you want to merge OBJ files together into a single larger file but still preserve vertex normals which unfortunately other freely available programs have a tendency to discard.


When you run it, it will show a simple dialog and you build up an input files list either by pushing the "Add files" button which lets you use the file open dialog (w/multi select) or by drag/dropping files on to the dialog window.

If you want to start over you can hit the Clear button to blank out the input files.

Then when you have all your input files listed up, you push the "Generate merged file" button which will ask you for a filename to write and then crunch out one single OBJ file that has all the other stuff combined into it.

Most things like object names and vertex data pass straight through to the combined file, but the index values of all faces are adjusted to make them correct in the new vertex list and also it gathers up all the materials used by every file and puts that out into one combined material file as well.

Hope it's useful!

Not just useful, in fact, absolutely essential for the job I've got to do.

It works perfectly too but I don't reckon that will be any surprise to anyone on the forum.

Cheers!

A cool one to add on the French wiki parts ;)

Wow, that's an awesome 60kb!!

Thanks for the utility, works great and will save a lot of Tylenol.

I shared your pain, now happily cured by Dr Gibson!
