Kaolin: A Pytorch Library for Accelerating 3D Deep Learning Research
Overview
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.
Installation and Getting Started
Starting with v0.12.0, Kaolin supports installation with wheels:
# Replace TORCH_VERSION and CUDA_VERSION with your torch / cuda versions
pip install kaolin==0.12.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-{TORCH_VERSION}_cu{CUDA_VERSION}.html
For example, to install kaolin 0.13.0 over torch 1.12.1 and cuda 11.3:
pip install kaolin==0.13.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-1.12.1_cu113.html
We now support version 0.12.0 to 0.13.0
Visit the Kaolin Library Documentation to get started!
About the Latest Release (0.13.0)
With the version 0.13.0 we have added new lighting features, most notably spherical gaussian diffuse and specular reflectance, we also improved the spherical harmonics API and coefficients.
See tutorials below.
We also:
- Reformated the data preprocessing with a new CachedDataset replacing ProcessedDataset
- Fixed bug and improved speed on SPC raytracing, and added gradient on trilinear interpolation
- Improved memory consumption on uniform_laplacian
Check out our new tutorials:
- Recipe for fast mesh sampling preprocessing in examples/recipes/preprocess/fast_mesh_sampling.py
- Recipe for SPC 3d convolution in examples/recipes/spc/spc_conv3d_example.py
- Tutorial for diffuse lighting in examples/tutorial/diffuse_lighting.ipynb
- Tutorial for spherical gaussian specular lighting examples/tutorial/sg_specular_lighting.ipynb
See change logs for details.
