Download and extract the dataset

Run the following commands to download and extract the dataset:

1. Start by downloading 3DShapeNets using the following link:

wget http://3dshapenets.cs.princeton.edu/3DShapeNetsCode.zip

1. After you have downloaded the file, run the following command to extract the files to an appropriate directory:

unzip 3DShapeNetsCode.zip

We have now successfully downloaded and extracted the dataset. It contains images in the .mat (MATLAB) format. Every other image is a 3D image. In the next few sections, we will learn about voxels, which are points in 3D space.
