Error in building the project

Hi @chengzhag ,

I got the following error while building the project. Seems like there are some missing files.

Building pyrender...

It seems there is no directory called GL. Hence, any reference to headers included in it would probably throw an error.

Would appreciate your help with this.

~Cheers!

Hi @metro-smiles,

From what I understand, the mesh_fusion/fusion.py does import libfusiongpu when use_gpu set to True. But further experiments indicate that GPU is truely not used (with the help of nvidia-smi) and there is no speed difference between libfusiongpu and libfusioncpu. It seems like that there is a problem with mesh_fusion lib, which I did not notice and cannot provide further help.

However, the preprocessing of Pix3D is accelerated with multi-thread, which can be done in less than hour. Thus the problem seems not very significant.

Thanks for your summary for the compiling problem. We updated two recent commits to solving it.

Hi @emirhanKural,

We use the detection results provided by Total3D and Coop. However, the 2D detector is not included in their code.

The detections.json of the demo is converted from the provided detections. If you want to test on your own data, you have to either fine-tune a 2D detector on SUN-RGBD or fine-tune it on your own dataset and map the output categories.
