Thibault Groueix, Matthew Fisher, Vladimir G. Kim , Bryan C. Russell, Mathieu Aubry
In CVPR, 2018.

This implementation uses Python 3.6, Pytorch, Pymesh, Cuda 10.1.

  - [x] Factorize Single View Reconstruction and autoencoder in same class
  - [x] Factorise Square and Sphere template in same class
  - [x] Add latent vector as bias after first layer(30% speedup)
  - [x] Remove last th in decoder
  - [x] Make large .pth tensor with all pointclouds in cache(drop the nasty Chunk_reader)
  - [x] Make-it multi-gpu
  - [x] Add netvision visualization of the results
  - [x] Rewrite main script object-oriented
  - [x] Check that everything works in latest pytorch version
  - [x] Add more layer by default and flag for the number of layers and hidden neurons
  - [x] Add a flag to generate a mesh directly
  - [x] Add a python setup install
  - [x] Make sure GPU are used at 100%
  - [x] Add f-score in Chamfer + report f-score
  - [x] Get rid of shapenet_v2 data and use v1!
  - [x] Fix path issues no more sys.path.append
  - [x] Preprocess shapenet 55 and add it in dataloader
  - [x] Make minimal dependencies
  

• Learning Elementary Structures
• 3D-CODED
• Cycle Consistent Deformations
• Atlasnet code V2.2 (more linear, script like, may be easier to understand at first)
