The shader in this example uses depth information from a p5.Framebuffer to apply a blur. On a real camera, objects appear blurred if they are closer or farther than the lens’s focus. This simulates that effect. First, the sketch renders five spheres to the framebuffer. Then, it renders the framebuffer to the canvas and applies the blur shader, which is written in p5.strands.
