Dear Professor, I mean calculating local integration as in "space is the machine".and I asked it based on Daniel Koch's comment: "correctly R3 in space is the machine equals radius 2 in Depthmap". I entered raduis 3 in my previous practices. now, I dont know what is the correct radius amount for local integration in depthmap? is it 2 or 3?.
