  • The assignment was good.
  • The explanation could use some work. While the flocking pseudocode and diagrams were nice, it took me a while to map the diagrams to the arrays in the base code. From the diagram, I thought Grid Cell Index and Boid index were one structure as key, value. Eventually, I finally understood that they are two separate arrays.
  • For the Coherent part, I had to change my thinking. Before, I was thinking of the kernel index as the boid index. However, that doesn't work anymore for Coherent because we do not have access to the boid index. Rather, the index correlates to a position in the pos/vel array, whichever boid that may be.
