Quartz Composer Fundamentals - Shapes from GL Lines and Iteration





I've made three example compositions (Line Cone, Line Sphere, and Line Spirograph) available at the Kineme Composition Repository. These three compositions show how to use a GL Line (GL Tools Required), Iteration, LFO's, and Interpolation, to make two basic shapes, and one animated spirograph, in Quartz Composer. These have the visual advantage of having a two color gradient available, as well as stipple repeat controls, which can make many interesting patterns when manipulated further. By going inside the patch, and changing LFO types, and Interpolation curves, even more shapes can be made.
