Without Anti-Aliasing

Perfect


Test I - limited at about 4 samples per pixel

double size and scaling - 4.00 SPP

Method 1 (old) [+AM1 +A0.5 +R3 +J1] - 5.19 SPP

Method 2 (old) [+AM2 +A.05 +R2 +J1] - 2.44 SPP


Method 2 (old) [+AM2 +A1 +R3 +J1] - 6.25 SPP


Method 3 (like 2 but mostly using less SPP)

nearly the same as method 2

Method 4 [+AM4 +A0.3 +R2 +J1] - 5.14 SPP (updated)


Method 5 (like 4 but forcing midpoint always traced) [+AM5 +A1.1 +R2 +J1] - 4.78 SPP (updated)



Test II - limited at about 9 samples per pixel

triple size and scaling - 9.00 SPP

Method 1 (old) [+AM1 +A0.2 +R4 +J1] - 9.92 SPP

Method 2 (old) [+AM2 +A0.5 +R3 +J1] - 15.96 SPP


Method 3 (like 2 but mostly using less SPP) [+AM3 +A0.3 +R3 +J1] - 15.61 SPP


Method 4 [+AM4 +A0.35 +R3 +J1] 13.32 SPP (updated)


Method 5 (like 4 but forcing midpoint always traced) [+AM5 +A.35 +R3 +J1] - 13.88 SPP (updated)
