3D DCGAN inspired GAN trained on 32x32x32 voxelizations of Thingi10k - a corpus of 10,000 3D printable objects and sculptures - as a result, the generated sculptures are almost always 3D-printable, but usually do not have any real 'meaning', and are just abstract sorts of shapes.
I originally began this project as an attempt at generative architecture; but lack of an appropriate dataset held me back from that. Currently working with trying to get something usable from the google sketchup 3d workshop
There are really only 3 files you need to use to generate your own 3D shapes.
You need to download Thingi10k, and in line 8 of generate_dataset.py, set the variable path_to_dataset to be the path to your raw_meshes folder from your thingi10k download.
Next, just run the file with python generate_dataset.py, and it will start generating numpy arrays that contain all of the now-voxelized models in thingi10k and save them to your data/ folder.
On line 23 of train.py, point it to the desired (usually the largest) .npy file in your data/ folder by setting numpy_array_saved equal to its path.
Then, you can just run python train.py and trained network checkpoints will start to populate your network_checkpoints/ folder.
Point visualize.py to an array of generations in your generations folder (an array is created every 50 epochs) by setting array_to_visualize equal to its path.
This script will allow you to see the models that network has generated in 3D, with the option to save as PNG, obj, etc.
Right now, the main issue is the fact that it's very hard to get data for this sort of project; the only two datasets I have encountered are shapnet and thingi10k; currently; i am trying to train a conditional version of the 3d GAN with shapenet so that you can select that you want to generate a table, chair, etc, and the network will move past just generating "shapes"...
