How to Voxelize Meshes and Point Clouds in Python

This article goes through the steps of generating voxel representations of point clouds and meshes using four widely popular Python libraries — Open3D, Trimesh, PyVista, and pyntcloud. Voxelization is an important pre-processing step for a lot of 3D deep learning models. The article shows how to calculate voxel level features like colors, point density, and occupancy among others. Finally, a demonstration of how to create simple interactive voxelization and thresholding examples is also given. Who said …
