We previously mentioned that picking based on the diffuse property could be difficult if two or more objects in the scene share the same diffuse color. If that were the case and you selected one of them, how could you determine which one is picked based on its color? In the following Time for Action section, we will implement unique object labels. The objects will be rendered in the offscreen framebuffer using these color labels instead of the diffuse colors. The scene will still be rendered on the screen using the non-unique diffuse colors.

Overview of this book
As highly interactive applications have become an increasingly important part of the user experience, WebGL is a unique and cutting-edge technology that brings hardware-accelerated 3D graphics to the web.
Packed with 80+ examples, this book guides readers through the landscape of real-time computer graphics using WebGL 2. Each chapter covers foundational concepts in 3D graphics programming with various implementations. Topics are always associated with exercises for a hands-on approach to learning.
This book presents a clear roadmap to learning real-time 3D computer graphics with WebGL 2. Each chapter starts with a summary of the learning goals for the chapter, followed by a detailed description of each topic. The book offers example-rich, up-to-date introductions to a wide range of essential 3D computer graphics topics, including rendering, colors, textures, transformations, framebuffers, lights, surfaces, blending, geometry construction, advanced techniques, and more. With each chapter, you will "level up" your 3D graphics programming skills. This book will become your trustworthy companion in developing highly interactive 3D web applications with WebGL and JavaScript.
