  We propose NerfAcc, a toolbox for efficient volumetric rendering of radiance
fields. We build on the techniques proposed in Instant-NGP, and extend these
techniques to not only support bounded static scenes, but also for dynamic
scenes and unbounded scenes. NerfAcc comes with a user-friendly Python API, and
is ready for plug-and-play acceleration of most NeRFs. Various examples are
provided to show how to use this toolbox. Code can be found here:
https://github.com/KAIR-BAIR/nerfacc. Note this write-up matches with NerfAcc
v0.3.5. For the latest features in NerfAcc, please check out our more recent
write-up at arXiv:2305.04966
