Book Description
Over 90 ready-to-serve, real-time rendering recipes on Android and iOS platforms using OpenGL ES 3.0 and GL shading language 3.0 to solve day-to-day modern 3D graphics challenges
In Detail
"Write once, use anywhere" is truly the power behind OpenGL ES and has made it an embedded industry standard. The library provides cutting-edge, easy-to-use features to build a wide range of applications in the gaming, simulation, augmented-reality, image-processing, and geospatial domains.
The book starts by providing you with all the necessary OpenGL ES 3.0 setup guidelines on iOS and Android platforms. You'll go on to master the fundamentals of modern 3D graphics, such as drawing APIs, transformations, buffer objects, the model-view-project analogy, and much more. The book goes on to deal with advanced topics and offers a wide range of recipes on the light shading, real-time rendering techniques with static and procedure textures to create stunning visualizations and runtime effects.
