The GLPaint sample application demonstrates how to support single finger painting using OpenGL ES. This sample also shows how to detect a "shake" motion of the device. By looking at the code you'll see how to set up an OpenGL ES view and use it for rendering painting strokes. The application creates a brush texture from an image by first drawing the image into a Core Graphics bitmap context. It then uses the bitmap data for the texture.
