Processing for Android (2nd Ed., 2nd ed.) Create Mobile, Sensor-aware, and XR Applications Using Processing
Langue : Anglais
Auteur : Colubri Andrés
Learn how to use the Processing programming language and environment to create Android applications with ease. This book covers the basics of the Processing language, allowing users to effectively program interactive graphics in 2D, 3D, and Extended Reality (XR). It also details the application of these techniques to different types of Android devices (smartphones, tablets, wearables, and smartwatches).
This updated edition walks you through the entire process of creating an app, from the initial idea to release of the final app via the Google Play App Store. Over the course of the book, you?ll learn to write engaging apps driven by user interaction and sensor data. A comprehensive series of hands-on projects, ranging from simple sketches to more complex projects involving shaders, VR, and AR will give you the firsthand experience you need to begin developing your own projects.
And once you have your Processing projects completed, you?ll be able to upload them to the Google Play store to be shared with the world!

3) Sending location data between devices
4) Storing and representing paths
Part IV: Wearables and watch faces
Wearables are a whole new category of Android devices that became very popular in the past few years, particularly in the form of fitness bands and smartwatches. Processing for Android lets you run your sketches on these devices and take advantage of their multiple affordances.Chapter 10: Wearable Devices
1) Android wear and wearable devices
2) Smartwatches and their unique capabilities
3) Adapting Processing sketches to run on smartwatches

2) Visualizing activity in real-time
3) Storing activity data for later use
Part V: 3D and Shaders
Interactive 3D scenes are an important part of creating visualizations and immersive experiences on mobile devices, especially with the recent rise in popularity of Virtual Reality. The programming of 3D scenes adds further complexity to the code sketching, but Processing provides a simplified 3D API to help with this task, while also giving access to advanced programming techniques such as GLSL shaders.
