Faces not being unsubdivided on OBJ export?

[dylanlacewell]

I downloaded the prebuilt binary for Windows without Gurobi. Running this series of steps in the gui produces an output OBJ file with roughly 4x the number of faces as the input OBJ:

• Load Mesh
• Calculate Quad Layout
• Calculate Parameterization
• Save Textured Mesh

This seems to be true even for models such as " beetle_refined.obj_surout.obj" that contain mostly quads. The paper claims any extra faces from subdivision should be mostly removed again on export, and I see the unsubdivide step enabled by default for Data::SaveMeshOBJ,. So I am puzzled by this result:

// number of input faces
$ grep -c "f " beetle_refined.obj_surout.obj
8518

// number of output faces
$ grep -c "f " out.obj
34388

Hi, thanks for your bug report. Actually, the application does un-subdivide. You can verify that by visually inspecting the wireframe of the result. But for some reason, faces are duplicated. I'm going to invest this once I have time to spare.

Ah, I see. Thanks for looking at it. I should have checked the wireframe before jumping to conclusions based on the number of output faces only.
