This document discusses high performance graphics and compute using OpenGLES and RenderScript on Android. It begins with an introduction to graphics terms like primitives and textures. It then covers how graphics are handled by the GPU, describing the graphics pipeline and shader programs. It discusses using OpenGLES for Android graphics, including the GLSurfaceView class. RenderScript is introduced as a way to access the GPU for general purpose computing through a high-level API, with examples of image processing, encryption, and other applications.
