what mip mean in the code

[neilgogogo]

Thank you for the excellent work, I have a question about the code.

I saw many mip in the code, what does mip mean?

instant-ngp/src/testbed_nerf.cu

Line 1022 in 1f40048

uint32_t mip = mip_from_dt(dt, pos);

Many thanks

Hi there, mip is short for "mipmap level" and refers to the level of the multi-resolution occupancy grid that is to be used for empty-space skipping. (described in Appendix C of the paper)
