From my understanding, Moire patterns, the aliasing occurring in this image, are derived from the superposition of two patterns with different frequencies. The two patterns are the image pattern and our sampling "pattern".
My question is - how does downsampling help with the superposition issue? Or, how does downsampling approximate the "real solution", numerically computing the difference in frequency? (finding dp in this reference: https://en.wikipedia.org/wiki/Moir%C3%A9_pattern#Calculations)
I think this is a good example of how nearest/linear level sampling is crucial. It is not very apparent in our assignment 1 SVG's because they are all 2D. But in 3D scenes such as this one, the same texture being used at different depths makes level sampling almost a requirement.
