How to conduct fair comparison between baselines and OmniSDF?

[ShntrIto]

Hi authors,
Thank you for your great project!
I have some questions regarding the experimental settings and evaluation as below:

1. How did you ensure a fair comparison between COLMAP, NeuS-facto, Neuralangelo, and OmniSDF?
2. In the paper, you mentioned that omnidirectional images are converted int six-face perspective cube maps. Did you estimate the intrinsics and extrinsics for each cube map face using COLMAP?
3. If the estimated camera parameters were used for baselines, I belive that their scale would differ from the GT camera parameters. In that case, how did you ensure a fair evaluation of the rendered depth maps?
4. Could you provide guidance on reproducing your experimental results through SDFStudio with the GT (or estimated) camera parameters?

I would greatly appreciate any insights you can share, even if you can only answer some of above questions.
Thank you!!
