Smoothstep isn’t that great for AA… X axis is distance to edge; Y axis is area of pixel covered. Blue = true area, green = smoothstep.pic.twitter.com/z5rZVIbwyH

I’m confused. Your pixel square doesn’t have length 1 in both drawings (in the second it’s sqrt(2)/2).
The area of your second square is 0.5, so if I’m not mistaken the fraction of the total area is 0.25, same as the first square.
I’m using proportions. Count the triangles. Each quadrant has 4. Each is 1/16 of the total. Only 2 are covered, i.e. 1/8 of the total pixel area.
