Scale/ Offset and depth map

[meriemjabri]

Hello,
I want to use my own dataset, which consists of an unbounded forward facing scene, but I don't know how to choose the scale and offset to use in the transforms.json file (my values are in meters). I also saw that the depth map was used. Was this done with instant-ngp depth supervision?
I tried to use my own depth map but I think the value of integer_depth_scale is not the right one. I just used max_value/65535 for this but I think the max_value should also be converted to another unit. I would be grateful for any feedback or ideas you may have.

If I'm not mistaken, instant-ngp is just not capable of accurately dealing with infinite-depths. This was also always clear when using the lone monk scene fro the paper: the blue sky just floats a few meters above the courtyard: it looks good from the viewpoints in the dataset, but when you move around a bit further, you start seeing that it's not actually in the right place.
