One of HTML5’s most exciting features, Canvas provides a powerful 2D graphics API that lets you implement everything from word processors to video games. In Core HTML5 Canvas, best-selling author David Geary presents a code-fueled, no-nonsense deep dive into that API, covering everything you need to know to implement rich and consistent web applications that run on a wide variety of operating systems and devices. Succinctly and clearly written, this book examines dozens of real-world uses of the Canvas API, such as interactively drawing and manipulating shapes, saving and restoring the drawing surface to temporarily draw shapes and text, and implementing text controls. You’ll see how to keep your applications responsive with web workers when you filter images, how to implement smooth animations, and how to create layered, 3D scrolling backgrounds with parallax. In addition, you’ll see how to implement video games with extensive coverage of sprites, physics, collision detection, and the implementation of a game engine and an industrial-strength pinball game. The book concludes by showing you how to implement Canvas-based controls that you can use in any HTML5 application and how to use Canvas on mobile devices, including iOS5. This authoritative Canvas reference covers The canvas element—using it with other HTML elements, handling events, printing a canvas, and using offscreen canvases Shapes—drawing, dragging, erasing, and editing lines, arcs, circles, curves, and polygons; using shadows, gradients, and patterns Text—drawing, positioning, setting font properties; building text controls Images—drawing, scaling, clipping, processing, and animating Animations—creating smooth, efficient, and portable animations Sprites—implementing animated objects that have painters and behaviors Physics—modeling physical systems (falling bodies, pendulums, and projectiles), and implementing tweening for nonlinear motion and animation Collision detection—advanced techniques, clearly explained Game development—all aspects of game development, such as time-based motion and high score support, implemented in a game engine Custom controls—infrastructure for implementing custom controls; implementing progress bars, sliders, and an image panner Mobile applications—fitting Canvas apps on a mobile screen, using media queries, handling touch events, and specifying iOS5 artifacts, such as app icons Throughout the book, Geary discusses high-quality, reusable code to help professional developers learn everything they really need to know, with no unnecessary verbiage. All of the book’s code and live demonstrations of key techniques are available at corehtml5canvas.com.
Apple’s Core Animation framework enables Mac OS X, iPhone, and iPod touch developers to create richer, more visual applications–more easily than ever and with far less code. Now, there’s a comprehensive, example-rich, full-color reference to Core Animation for experienced OS X and iPhone developers who want to make the most of this powerful framework. Marcus Zarra and Matt Long reveal exactly what Core Animation can and can’t do, how to use it most effectively–and how to avoid misusing it. Building on your existing knowledge of Objective-C, Cocoa, and Xcode, they present expert techniques, insights, and downloadable code for all aspects of Core Animation programming, from keyframing to movie playback. Zarra and Long thoroughly review similarities and differences between Core Animation on the Mac and iPhone, helping you write code that can easily move between platforms. They also present a full chapter of innovative techniques and proven “rules of thumb” for optimizing Core Animation’s real-world performance. Coverage includes: Taking full advantage of Core Animation’s lightweight layers and views Using keyframes to gain complete control over your animations Creating startling effects with Core Animation transforms Leveraging Core Image’s powerful filtering capabilities from within Core Animation Playing QuickTime movies using Core Animation’s QTMovieLayer Using the OpenGL layer to achieve greater control over movie playback Integrating advanced Quartz Composer visualizations into your user interfaces How to use helper layers to draw gradients, composite shapes, and replicate sublayers Adding mouse and keyboard user interaction points, and much more...
Computer Graphics from Scratch demystifies the algorithms used in modern graphics software and guides beginners through building photorealistic 3D renders. Computer graphics programming books are often math-heavy and intimidating for newcomers. Not this one. Computer Graphics from Scratch takes a simpler approach by keeping the math to a minimum and focusing on only one aspect of computer graphics, 3D rendering. You’ll build two complete, fully functional renderers: a raytracer, which simulates rays of light as they bounce off objects, and a rasterizer, which converts 3D models into 2D pixels. As you progress you’ll learn how to create realistic reflections and shadows, and how to render a scene from any point of view. Pseudocode examples throughout make it easy to write your renderers in any language, and links to live JavaScript demos of each algorithm invite you to explore further on your own. Learn how to: Use perspective projection to draw 3D objects on a 2D plane Simulate the way rays of light interact with surfaces Add mirror-like reflections and cast shadows to objects Render a scene from any camera position using clipping planes Use flat, Gouraud, and Phong shading to mimic real surface lighting Paint texture details onto basic shapes to create realistic-looking objects Whether you’re an aspiring graphics engineer or a novice programmer curious about how graphics algorithms work, Gabriel Gambetta’s simple, clear explanations will quickly put computer graphics concepts and rendering techniques within your reach. All you need is basic coding knowledge and high school math. Computer Graphics from Scratch will cover the rest.
