About the performance on Lego, using Instant-NGP. #101

Closed helcpp closed 1 year ago

helcpp commented 1 year ago

It's a great job. It helps me a lot. In the case of Instant-NGP, the Lego results had a slightly lower PSNR than in the paper, about 35.69. Which parameter should I adjust to improve my accuracy? This question makes me very confused and I am looking forward to your reply.

Here is my output:
