Metal enables Apple developers to maximize performance in demanding tasks like 3D graphics, games, scientific programming, visualization, and GPU-accelerated machine learning. Metal® Programming Guide is the authoritative, practical guide to Metal for all iOS programmers who are interested in graphics programming but don’t know where to start.
Pioneering Apple developer Janie Clayton covers everything from basic draw calls to advanced parallel computing, combining easy-to-understand conceptual explanations with well-tested Swift 4/Xcode 9 sample code (available for download at GitHub).
Clayton introduces the essential Metal, graphics, and math concepts every graphics programmer needs to know. She also discusses key graphics-specific libraries, concepts, and Metal Classes, presenting techniques and examples you’ll find valuable for both graphics and data processing. Clayton also provides coverage of the Metal Compute Pipeline, demonstrating practical GPU programming applications ranging from image processing to neural networking.
Quickly get a basic Metal project running
Work with Metal resources and memory management
Learn how shaders are compiled and accessed by the CPU
Program both 2D and 3D graphics with Metal
Import 3D models and assets from Blender, Maya, and other programs
Apply imported textures to model objects
Use multipass rendering to efficiently implement computationally expensive techniques
Leverage tessellation to reduce mesh detail
Use the GPU for a wide spectrum of general-purpose computing applications
Get started with the Metal Performance Shaders Framework
Janie Clayton is an independent iOS developer and graphics programmer. Janie is the author on several books on iOS and Swift development, including the Swift Apprentice and iOS 10 SDK. She records her journey down the rabbit hole on her personal blog at http://redqueencoder.com. Janie lives outside of Madison, Wisconsin, with her attempted grumble of pugs and multitude of programming books.
