Kaolin: A Pytorch Library for Accelerating 3D Deep Learning Research


NVIDIA Kaolin library provides a PyTorch API for working with a variety of 3D representations and includes a growing collection of GPU-optimized operations such as modular differentiable rendering, fast conversions between representations, data loading, 3D checkpoints and more.

Kaolin library is part of a larger suite of tools for 3D deep learning research. For example, the Omniverse Kaolin App allows interactive visualization of 3D checkpoints. To find out more about the Kaolin ecosystem, visit the NVIDIA Kaolin Dev Zone page.

Installation and Getting Started

Visit the Kaolin Library Documentation to get started!

About the Latest Release (0.10.0)

With the version 0.10.0 we are focusing on Volumetric rendering, adding new features for tetrahedral meshes, including DefTet volumetric renderer and losses, and Deep Marching Tetrahedrons, and adding new primitive operations for efficient volumetric rendering of Structured Point Clouds, we are also adding support for materials with USD importation.

Finally we are adding two new tutorials to show how to use the latest features from Kaolin. See Tutorial Index for more.
