This was a really challenging exercise. Sadly, there was a lot I wanted to do but just couldn’t seem to figure out. Ideally, the shape of the hills would’ve matched the position of the trees but because the X placement of the trees from the beginning was random, I couldn’t create a linkage by chronological order of birth (a for loop would’ve been great for that).
I think I definitely have a better understanding of objects and creating generative landscape images, a far cry from past projects generative art.
