128.npz voxel files are not TDF

Hi, we used voxels instead of TDF for supervision. Could you point me to the issue that mentioned we used TDF so that I could further clarify on this confusion? Thanks.

Thanks for getting back to me @xiumingzhang.

It was mentioned on issue #46 that TDFs were used for supervision. If possible, I would be grateful if you mention the voxelization tool that was used or provide a piece of code for it.

Bests,
Aria

Oh there, by "TDF" what we really meant is "voxels with values in [0, 1], as opposed to binary voxel values." Sorry for the confusion, and please feel free to reopen if you have more questions.

I computed view-centered binary voxels using the binvox and then converted them to npz files. The way I do view-centered supervision is fixing the camera at a constant distance from the origin and then I rotate the object and get the renders for different views. I tried training marrnet 2 with the default settings for 100 epochs and the loss for the last 10s of epochs oscillated around 0.05. I then tried finetuning the marrnet using the pre-trained marrnet1 network, but the reconstruction results are not looking good at all!
I have attached the predicted output for a sample shape and also provided the voxel and depth maps used for training.

Thanks for your help.
