✦ Synopsis

Welcome to the latest volume of ShaderX! This all-new collection is packed with insightful new techniques, innovative approaches to common problems, and practical tools and tricks that will help you in all areas of shader programming. All of the articles evolved from the work and experiences of industry pros, and all of the sections were edited by shader programming experts. With the rapid advances in DirectX, OpenGL, and graphics cards, vertex and pixel shaders are becoming more widely used in high-end graphics and game development. The challenges of mastering these techniques can be daunting for new programmers, but with this comprehensive collection of ready-to-use techniques, they'll get up to speed quickly. And for the more experienced programmers, they'll find insights and tricks that will improve their efficiency and prevent redundancy. If you are involved in shader programming, this is a must-have reference for your collection.
