Datasets

We use the ShapeNet and Pix3D datasets in our experiments, which are available below:

• ShapeNet rendering images: http://cvgl.stanford.edu/data2/ShapeNetRendering.tgz
• ShapeNet voxelized models: http://cvgl.stanford.edu/data2/ShapeNetVox32.tgz
• Pix3D images & voxelized models: http://pix3d.csail.mit.edu/data/pix3d.zip

Pretrained Models

The pretrained models on ShapeNet are available as follows:

• Pix2Vox-A (457.0 MB)
• Pix2Vox-F (29.8 MB)

Prerequisites

Clone the Code Repository

git clone https://github.com/hzxie/Pix2Vox.git

Install Python Denpendencies

cd Pix2Vox
pip install -r requirements.txt

Update Settings in config.py

You need to update the file path of the datasets:

__C.DATASETS.SHAPENET.RENDERING_PATH        = '/path/to/Datasets/ShapeNet/ShapeNetRendering/%s/%s/rendering/%02d.png'
__C.DATASETS.SHAPENET.VOXEL_PATH            = '/path/to/Datasets/ShapeNet/ShapeNetVox32/%s/%s/model.binvox'
__C.DATASETS.PASCAL3D.ANNOTATION_PATH       = '/path/to/Datasets/PASCAL3D/Annotations/%s_imagenet/%s.mat'
__C.DATASETS.PASCAL3D.RENDERING_PATH        = '/path/to/Datasets/PASCAL3D/Images/%s_imagenet/%s.JPEG'
__C.DATASETS.PASCAL3D.VOXEL_PATH            = '/path/to/Datasets/PASCAL3D/CAD/%s/%02d.binvox'
__C.DATASETS.PIX3D.ANNOTATION_PATH          = '/path/to/Datasets/Pix3D/pix3d.json'
__C.DATASETS.PIX3D.RENDERING_PATH           = '/path/to/Datasets/Pix3D/img/%s/%s.%s'
__C.DATASETS.PIX3D.VOXEL_PATH               = '/path/to/Datasets/Pix3D/model/%s/%s/%s.binvox'

Get Started

To train Pix2Vox, you can simply use the following command:

python3 runner.py

To test Pix2Vox, you can use the following command:

python3 runner.py --test --weights=/path/to/pretrained/model.pth

If you want to train/test Pix2Vox-F, you need to checkout to Pix2Vox-F branch first.

git checkout -b Pix2Vox-F origin/Pix2Vox-F
