NVIDIAGameWorks/kaolin

Provides GPU-optimized operations for multi-representation 3D workflows including differentiable mesh rendering (DIB-R), fast format conversions, Structured Point Cloud acceleration structures, and physics simulation with collision detection. Integrates differentiable camera and lighting APIs with spherical harmonics/gaussians, plus native support for 3D gaussian splats and volumetric rendering modes. Built on CUDA kernels and designed for end-to-end differentiable pipelines across neural rendering, geometry optimization, and simulation tasks.
