Lecture 5: Texture Mapping (58)

This picture looks very counter-intuitive to me... Why does the further point have aliasing while the closer point doesn't? Aren't the further point where each pixel is representing many bricks? How come that one has aliasing with the loser point where many pixels represent a single brick does not?


To my understanding the further point has aliasing, because the signal has higher frequency at the further point. It has a higher frequency since the signal will change more rapidly in terms of color given the larger number edges in the same area. So in order to not have aliasing, we would need to sample at a higher rate at the further point.


I was wondering how is the fact that this is a full resolution texture important here? how does resolution play out in this slide and later slides?
