For my project this week, I wanted to make something that wouldn’t have the most common approach among the class. I figured that a lot of people would look to do a horizontal landscape, where there is a lot of movement with the X position. Therefore, I decided to do the house from Up but moving vertically!
I referred to images of the actual house from the Up animation to try to recreate it with shapes. This was not too difficult because I have gotten used to recreating specific images through layering shapes in p5js. However, the most difficulty I had with this assignment was with making the clouds reappear after they disappear off of the canvas. (I actually had to go to OH for a while for this.. thanks Peter for the help.)
One thing I wish I could have done differently though, is thinking through the concept more. Once I had basically established all of the objects I made, and had movement, I realized that by making the house go “into the sky” there wasn’t much more detail I could add other than birds. I guess with doing things horizontally, there are a lot more realistic features you could add that would make sense (such as mountains or trees).
