Processing Tutorial – Making Shapes
Circles We use the ellipse() function for circles because an ellipse is a rounded shape like an oval. ellipse(50,50,50,50); coordinate grid ellipse(50,40,35,70); Rectangles rect(10,10,80,80); coordinate grid rect(10,20,80,40); Triangles triangle(10,10,90,50,10,90); coordinate grid triangle(10,10,90,10,50,90); Other Shapes You can create lots of other shapes in Processing, includ- ing arcs, lines, quads (otherwise known as shapes with 4 sides), […]
