NVIDIA Kaolin


Kaolin is a suite of tools 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.

NVIDIA Kaolin Wisp is a faster-paced library for research in neural fields, a sub-class of 3D representations that includes NERFs and Neural SDFs. Built on the foundations of the core Kaolin Library, Wisp provides modular functions, training scripts, mix-and-match components, and extensible interactive neural field visualizer to help researchers stay on the bleeding edge of this quickly evolving research area.

NVIDIA Omniverse Kaolin App is an interactive application for 3D deep learning researchers that allows inspecting 3D datasets, interactive visualization of 3D outputs of a model during training, and synthetic dataset rendering. Built on Omniverse Kit, the research application benefits from high-fidelity RTX rendering and will gain new functionality periodically from new extensions.

In combination, these tools can massively reduce the time needed to develop AI research for a wide range of 3D applications.
