I finally got to start doing animation! There are two main ways to do animation. The first is using Quartz and the second is with OpenGL-ES. Quartz is really simple to use and with it you can easily create 2-D animations. OpenGL-ES is for 2-D and 3-D animations and is much more powerful and much more difficult to use than Quartz. It takes advantage of various hardware acceleration mechanisms to draw things efficiently unlike Quartz. For this tutorial I made a paint application using both Quartz and OpenGL-ES. Using Quartz was much simpler for this application. Without prior knowledge of how OpenGL works, beginners might want to stick with Quartz for their 2-D creations.
