Kaolin: NVIDIA PyTorch library for 3D deep learning, Gaussian splats and differentiable rendering

What it supplies: Kaolin is NVIDIA's PyTorch library of reusable, GPU-optimised modules distilled from 3D deep learning research. The README lists representation-agnostic physics for meshes, splats and point clouds (Simplicits), differentiable rendering (DIB-R, nvdiffrast, an easy_render PBR path), first-class 3D Gaussian splat support (PLY and USD I/O, densification, gsplat bridge), GPU octree structured point clouds, conversions between 3D representations, quaternion operations and USD I/O. Useful for: - Load, optimise and render 3D Gaussian splat scenes. - Simulate objects with collisions from a splat or mesh. - Read and write USD-based 3D data in research pipelines. - Prototype interactive browser interfaces over 3D research using the client-server visualisation framework. First action: - Pick your PyTorch and CUDA versions, then install a pre-built wheel such as pip install kaolin==0.18.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-2.8.0_cu128.html. - Check the installation guide's compatibility matrix. - Try the tutorials linked for Gaussian splats and simulation. Prerequisites and limits: Pre-built wheels exist per torch and CUDA combination (the README's example uses kaolin 0.18.0 with PyTorch 2.8.0 and CUDA 12.8); other combinations need the compatibility matrix or a source install. It gives no VRAM figures in the text read. - The kaolin/non_commercial package is legacy and kept only for backward compatibility; new code should use the Apache-licensed modules. - Wheel availability is tied to specific torch and CUDA versions. - It is a research library. The README states Kaolin is released under the Apache License 2.0, with a legacy kaolin/non_commercial package kept for old import paths that new code should avoid. Data you process carries its own rights. Written from the README text only. Statements are as the README gives them; nothing was installed or run.
