Hi @fyu , can you please share the script that converting the ModelNet dataset (e.g. ModelNet40) to the tensor file like modelnet40_r_12_v_30_train_images.tensor? Thanks a lot.

Hi @lidong04, you can use the code in https://github.com/fyu/util3d to convert the models in ModelNet to voxels and use the matlab/python io utilities in marvin to convert the voxels to tensor files.
