Instant-NGP
====================

See code at our github repository: https://github.com/KAIR-BAIR/nerfacc/tree/master/examples/

Benchmarks
------------

We trained on NeRF-Synthetic trainval set using TITAN RTX, and evaluated on testset.
Note Instant-NGP's results are taken from the paper, which is trained on a Nvidia 3090,
with random background trick using alpha channel.
