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.

With the version 0.12.0 we have added a Camera API, allowing to use all our renderers and multiple coordinate systems.

Checkout our news tutorials:

• plenty of camera recipes in examples/recipes/camera
• a tutorial using the new camera API with nvdiffrast examples/tutorial/camera_and_rasterization.ipynb

See change logs for details.

Please review our contribution guidelines.

• NVIDIA Kaolin Wisp:
  • Use Camera API, Structured Point Clouds and its rendering capabilities
• gradSim: Differentiable simulation for system identification and visuomotor control:
  • Use DIB-R rasterizer, obj loader and timelapse
• Learning to Predict 3D Objects with an Interpolation-based Differentiable Renderer:
  • Use Kaolin's DIB-R rasterizer, camera functions and Timelapse for 3D checkpoints.
• Neural Geometric Level of Detail: Real-time Rendering with Implicit 3D Surfaces:
  • Use SPC conversions and ray-tracing, yielding 30x memory and 3x training time reduction.
• Learning Deformable Tetrahedral Meshes for 3D Reconstruction:
  • Use Kaolin's DefTet volumetric renderer, tetrahedral losses, camera_functions, mesh operators and conversions, ShapeNet dataset, point_to_mesh_distanceand sided_distance.
• Text2Mesh:
  • Use Kaolin's rendering functions, camera functions, and obj and off importers.
