Try these freq/time combinations: (0.5,0.25), (0.75,0.25), (2.1,0.5).

Look at this demo of temporal aliasing.

Here is a video showing the reverse-spinning aliasing.

So....how does all this relate to your HW6? In other words, how can you add anti-aliasing to your homegrown renderer?

You are going to do it, by doing jittered sampling - you will create multiple renders (by rendering subtly-vertex-shifted versions of your scene), and average the results by weighting the renders (pixel by pixel). This means you need:

• num. samples (renders) to create
• pixel shift (x,y) for each variation
• weight (contribution) for each variation
