Some questions about εmax #1

Closed yizhezhang0418 closed 2 months ago

Hi, thanks for your excellent work!!! I am confused about the εmax , which you have mentioned in chapter 4.3. How to define and calculate the εmax , I can not find a explanation in your paper. Could you please explain this? Thanks.

Hi! Thank you for your attention to our work. We have scaled the camera positions to a bounding box of [-1, 1] and set $\epsilon_{max}$ to 0.1 on data of all scales (https://github.com/Open3DVLab/NeuRodin/blob/main/nerfstudio/fields/neurodin_field.py#L268).

We have not tuned this parameter because we believe it will not have a significant impact on the results—just ensuring it is not set too small (missing natural level set constraints of large-scale features) or too large (resulting in high variance in normal estimates for most regions).
