`````` For this week’s landscape project, I decided to do a desert scene. I used the noise part in order to create different layers of the landscape essentially creating a foreground, midground, and a background. The front most layer, or the foreground, displays the most detailed landscape and with cacti silhouettes. I found it a bit challenging to create the randomly generated cacti that would move across the screen. I have yet to figure out how to actually place the cacti on top of the terrain.
