Visualizing computational limitations f(x,y) = sin(x²+y²) x,y∈(-200,200) The plot should be radially symmetric, though it only appears to be so around the originpic.twitter.com/axyIoO1mmu

you may want to try point sets with quasi Monte Carlo. For instance, a blue noise point set would drastically reduce aliasing artifacts. The aliasing you observe is mostly due to the Fourier spectrum of the sampling pattern used to integrate the function within each pixel.
i actually don't care about what the real plot looks like haha .. the real plot is actually rather boring .. thanks though

For good measure, here is the function with randomized sampling, which converts the patterns, caused by undersampling with structured samplepoints, into noise - though I agree that is not nearly as pretty :) (code https://www.shadertoy.com/view/wdVXRW )pic.twitter.com/hLAgRpXAIx
