Command line interface giving same 3D mesh as output about boundary-first-flattening HOT 6 CLOSED

Hi @rupeshchandgude, the texture coordinates are stored in the "vt" flag of the output file as per the obj standard: https://en.wikipedia.org/wiki/Wavefront_.obj_file

@rohan-sawhney Thanks Rohan. I am able to access those points.

@rohan-sawhney When I give my test mesh to command line as a input, Computation is yaking too much time as well as memory. Finally process is killed automatically due to full use of memory. I have attached obj file. This obj file actually created by converting ply file(which is generated by realsense camera).
Ply file : https://drive.google.com/file/d/1FFSrSCQvG1YU4AOeKdNElPYssgEsPGg9/view?usp=sharing
Obj File : https://drive.google.com/file/d/1AMs6x9k1ZoYT2m_Q1X75Gw2kkFJA2FCl/view?usp=sharing

Ply file also contains a RGB data fro every point. Is this thing making issue in my code?

Hi @rupeshchandgude, it seems like the drive links are broken, I'm not able to access the files.

@rupeshchandgude I was able to download the file and looked into what is going on. The memory blowup is a quick fix and I'll push a fix soon. However, the model itself is not a single or a few meshes, the entire model is basically a triangle soup (i.e., a bunch of individual triangles). In all, there are about 250,000 "meshes" (each consisting of 1-2 triangles). This is not a problem for the flattening algorithm which works just fine; however, the current bin packing algorithm (which places the meshes in the plane so that they don't overlap) in the codebase is quite slow at this scale. BFF needs a faster (and maybe simpler) strategy for bin packing so many meshes. In the meantime, you could maybe try joining the independent triangles into a larger pieces (you could do this by detecting all vertices with the same coordinates and assigning them a single index in the obj file) and then feeding those into BFF.

@rohan-sawhney Thanks for reply. I will try joining independent triangles into larger piece. Also can you please give me notification when you fix the memory blowup fix and update the repository.
