This week’s project was definitely a bit of a struggle. I originally intended to create a forest with multiple layers of trees that appeared at the highest points of the created terrain (similar to an assignment we had to do for Week 7). The inspiration for a forest landscape was from this past summer, when I went camping with my family at Sequoia Kings Canyon. However, while there do not appear to be any bugs in my code, the trees are not showing up on the other “layers” of the forest (see below for a rough sketch of what I intended to create).
