Questions regarding rescaling the scene #64

Open melhashash opened 2 years ago

melhashash commented 2 years ago

Hi, thanks for the project,

I have a couple of questions regarding the lines below, if I understand correctly, bds stores the near and far bounds for each pose. My questions are:

  1. Why the poses are scaled using bd_factor and sc?
  2. Why bd_factor is set to 0.75 and how this affect the results?
