NVIDIA’s Kaolin library just took another step forward with the release of version 0.18.0, introducing physics based collisions for Gaussian Splats, meshes, signed distance fields, and more. Thanks to the integration of the Simplicits framework with NVIDIA Warp under the hood, you can now watch splats deform and collide under gravity.

The Simplicits implementation includes full collision support, complete with tests to ensure stability and accuracy. Alongside it, Kaolin now features interpolated camera trajectories (with both a ready to use recipe and unit tests), making it easier to generate smooth cinematic motion for your scenes. The release also adds conversion functions to seamlessly switch between Polyscope camera parameters and Kaolin’s own, smoothing out multi-tool workflows.

On the technical side, the team has made Kaolin compatible with NumPy 2.0 and above, while converting the triangle hash code from Cython to C++.

If you’re attending SIGGRAPH, NVIDIA will be showcasing the new physics simulation tomorrow, Sunday, August 10, in Room 121-122. The hands-on lab will offer a guided look at Simplicits, its collision system, and how NVIDIA Warp makes it all possible.

The Kaolin library remains open sourced and Apache 2.0 licensed through GitHub.
