Support quad meshes about boundary-first-flattening HOT 5 CLOSED

We started testing this and it appears that the software doesn't successfully import any OBJ mesh other than the one that ships with the application. I attempted to import an OBJ exported from Maya, Max, Zbrush and Mudbox. All of them failed to import.

Can you try loading one of the meshes in the input/ subdirectory? Someone else we spoke with was also having trouble loading meshes; might be a file I/O problem rather than a mesh parser issue. (The face mesh is hard-coded into the executable, so it doesn't need to do any disk I/O).

Also helpful if you could attach some of the meshes you're trying to load to this thread.

Thanks!

I tried what you suggested and that didn't appear to work either. I've attached a few files for testing. Once of them is a simple Box (1 mesh, 1 poly island) and the Other is a Utah Teapot (1 mesh, 4 poly islands) from 3ds Max.

I also tried making the obj composed of only tri's and that didn't work either. Let me know if i can do anything else to help out.

Ok, actually several things going on here (listed below). Thanks for being a beta tester—clearly we still have a few kinks to work out in our OBJ support! :-)

• the OBJ files use negative face indices, which is not currently supported by our parser (but should be); I've created a new open issue #8 for this item
• some of the faces in the cube are quads rather than triangles, which is covered by this open issue (#4) but still needs to be implemented
• the teapot consists of multiple components, which is addressed by issue #6 and still needs to be resolved (again this is an easy fix: just map each object separately, but needs to be implemented)
• the teapot also has pieces (like the handle and spout) that have multiple boundary loops; here I've opened an issue #9 to cut them into single disks

In short: there are a lot of little things that need to be fixed, but ultimately shouldn't get in the way of unwrapping meshes like these—see the image below, where I've gone ahead and triangulated/cut the meshes in a modeler, and saved them w/ positive face indices.
