Leap Motion Development Essentials

By: Mischa Spiegelmock

Overview of this book

Leap Motion is a company developing advanced motion sensing technology for human–computer interaction. Originally inspired by the level of difficulty of using a mouse and keyboard for 3D modeling, Leap Motion believe that moulding virtual clay should be as easy as moulding clay in your hands. Leap Motion now focus on bringing this motion sensing technology closer to the real world. Leap Motion Development Essentials explains the concepts and practical applications of gesture input for developers who want to take full advantage of Leap Motion technology. This guide explores the capabilities available to developers and gives you a clear overview of topics related to gesture input along with usable code samples. Leap Motion Development Essentials shows you everything you need to know about the Leap Motion SDK, from creating a working program with gesture input to more sophisticated applications covering a range of relevant topics. Sample code is provided and explained along with details of the most important and central API concepts. This book teaches you the essential information you need to design a gesture-enabled interface for your application, from specific gesture detection to best practices for this new input. You will be given guidance on practical considerations along with copious runnable demonstrations of API usage which are explained in step-by-step, reusable recipes.

WebGL


Some old-timers may instinctively scoff at the notion of creating a 3D environment in a web browser, using only JavaScript (and maybe some GL shader language). Is it really supported by all modern browsers? Is it accelerated? Does it perform well on mobile devices? Does it have the same capabilities found in a native graphics library that I'd want?

Well, more or less yes. There may be some skeptics out there, especially those who remember the first real attempt at 3D graphics on the web long ago, using virtual reality markup language (VRML). That was an attempt to implement 3D animations with standardized markup rendered via browser plugins, and, quite honestly it was not all that awesome, and we should probably forget it ever existed. Those days are long behind us now, fortunately.

Let's talk about WebGL. It's a well-defined API standard maintained by the Khronos non-profit group, along with other OpenGL-related standards. It is supported by nearly all major browsers, with the usual...
