The app allows you to create abstract art-like images. You choose between a triangle, a circle and a rectangle as the basic shape, but the resulting image often looks much more sophisticated than the basic shape. Internally, the app uses fractal trap algorithm to count number of iterations falling within the basic shape. However, you dont need to know any mathematical details to produce intriguing images.
As with other versions of Poly-z-Vision you build intricate artistic images by moving a few points and tweaking simple controls. You can also easily adjust colors and make your images spiral, zoom, etc.
