Welcome to fVDB-Reality-Capture!

fVDB-Reality-Capture is a reality-capture toolbox built on top of fVDB. It provides high-level abstractions and APIs for common reality capture tasks, such as loading sensor data, reconstructing radiance fields, extracting meshes and point clouds, visualization, and exporting results across standard formats such as PLY and USDZ.

By leveraging the power of fVDB, fVDB-Reality-Capture can scale reconstruction to very large or dense inputs, while maintaining high performance and low memory usage. fVDB has 50% better throughput than gsplat in end-to-end training benchmarks and 30% lower runtime, while producing higher quality results and working out-of-the-box on a wide range of inputs. The videos below show large-scale reconstructions of complex scenes using fVDB-Reality-Capture.

About fVDB-Reality-Capture

fVDB and fVDB-Reality-Capture were first developed by the NVIDIA High-Fidelity Physics Research Group within the NVIDIA Spatial Intelligence Lab, and continues to be developed with the OpenVDB community to suit the growing needs for a robust framework for spatial intelligence research and applications.

fVDB-Reality-Capture is built on top of fVDB, which provides efficient GPU data structures and algorithms for working with sparse volumetric data. By leveraging the power of fVDB, fVDB-Reality-Capture can scale reconstruction to very large or dense inputs, while maintaining high performance and low memory usage.

fVDB and fVDB-Reality-Capture are open source under the Apache 2.0 license. We welcome contributions and feedback from the community.

For questions or feedback, please use the GitHub Issues for this repository.
