WebGL has emerged as a web technology for using OpenGL ES to provide truly zero-footprint hardware-accelerated 3D graphics in web pages. Written by experts in the OpenGL community, this book presents intermediate and advanced OpenGL techniques used in the real world. It demonstrates the large range of use cases and environments where OpenGL can make a difference, placing an emphasis on practical applications. Supported by Khronos, the book offers example problems with source code and addresses application architecture, IHV specific techniques, and interoperability.
