About threshold value in paper

[VitaLemonTea1]

Hi,
Thanks for releasing code. I see you set a threshold value to fliter out the occupied voxels in equ(3).
I found the threshold is 8.5 in code. I would like to ask why 8.5 was chosen instead of other values.

Hi, sorry for the late reply. The value 8.5 isn't necessarily the optimal threshold; it's an empirical value that performs well in most cases but hasn't been rigorously validated.

In early experiments, we determined this threshold by searching the validation set in increments of 0.5.
