Hi,
Can you run the newest example code on the fox dataset? The default num_levels
is 16
and it should be able to work.
As for the aabb_scale
, you could enlarge the --bound
parameter to achieve a similar effect (the scene is assumed to be bounded in Box[-bound, bound]
, so a larger bound allows the ray to travel further. For the fox dataset, the default bound=2
should work fine).

Thanks for the prompt reply! Sorry, there is a typo in the last message (num_levels=16
-> num_levels=32
). I tried to enlarge it to 32, but got the -inf/inf
issue.
For the bound, thanks and I will try that! it seems that the current implementation is doing uniform sampling in Box[-bound, bound]? However, in the original instant-ngp, they are doing uniform in unit cube, and exponential sampling in outside range?

- I tried 32 in the fox experiment and still didn't met
inf
, could you provide a reproducible example? (I just fixed a maybe related issue #11, you could try the latest version) - You are right, the current simple pytorch rendering function only performs uniform sampling. A better rendering that matches the original repo is still under development.

Closed for now.
