Scratch disc calculation
I am with the new project creating a tour with 3000 (+) nodes (20Kx10K pix each panorama) and I need a calculation for a needed scratch disk for p2vr to create a tour "in one piece". Example... each image is with 1GB size, so the basic scratch disk is 3 TBs + ? needed space. (I need the calculation because of buying SSD of the needed size , eg. Seagate Hellium, but not wating to buy oversized disc as at the moment is needed only for the current project).
Hello Bostjan,
you don't need to keep all panos in the scratch file, if you check "unload images" and disable "load all images" in the advanced settings.
If you still want to do it, the calculation goes like this:
width(px) × high(px) × 4 (colors RGBA) × 1.5 (image pyramid) =
20 000 × 10 000 × 6 = 1.2 GB per image
1.2 GB × 3 000 = 3.6 TB
This is some additional space used for remapping, but a 4 TB disc should do the trick

I forgot to add: If the image is 16bit, then the size is times 2... and for HDR it is times 4.
