This talk discusses high performance, fully dynamic WebGL, showing you how to get the most from WebGL when not dealing with static or pre-compiled models, and how to go about building a framework that allows for rapid, and efficient batching and submission of both 2D and 3D assets. You'll learn how to get the best performance by keeping a simple, yet flexible vertex buffer system - particularly for 2D, and how efficient texture pages will maximize your batching. While this talk is based around 2D, the framework is easily extended into 3D for things like particle systems.
