I'm just trying to understand a little better the use of some parameters.

In reconstruction settings/ normal mode you have the downscale image parameter.
I, of course understand what it means but want to understand how it works.
If you set the parameter to "2" is it like if your images were 2 times smaller ? or does it generate 50% the size of the regular depth map ?

Another question about "quality level" : le parameter is set to 1 in normal and 2 in high.
What is the max value ? how does it work ? is it possible to use 3 or 4 if you want to treat a little object (like a coin) ?

thanks.

Fred

  Hi toulbroch24

  its downsample the source images and just then are depth maps calculated
  yes 2x downsample is a reduction to 50%
  1x downsample = every pixel used
  2x dowsample = every 2nd pixel used
  3x downsample = every 4 pixel used
  4x downsample = every 8 pixel used

  OK as we discussed it with DEVs we will remove the quality settings from there so its not confusing you
  its have no impact on the meshing, its just internal "description".
  
  DRAFT = Q-0
  NORMAL = Q-1
  HIGH = Q-2
