For this portrait, I asked if my sister if I could use one of her older photos. For the project, I just played around with what variables I could randomize to make it more interesting. I decided to incorporate the three elementary shapes, a square, a triangle, and a circle to reconstruct my image. I also varied the size of the shapes that were used to reconstruct the image. Below are just some screen shots of the program, at it’s initial, intermediate, and “final” reconstruction of the image.
