Overview of this book

The drastic surge in the demand for XR development has led to an imminent need for comprehensive resources, learning material, and overall know-how in this area. This one-stop resource will ensure that professionals venturing into XR development can access all XR-related techniques to build appealing XR applications, without relying on Google every step of the way. This book is your guide to developing XR applications with Unity 2021.3 or later versions, helping you to create VR, AR, and MR experiences of increasing complexity. The chapters cover the entire XR application development process from setting up an interactive XR scene using the XR Interaction Toolkit or AR Foundation, adding physics, animations, continuous movement, teleportation, sound effects, and visual effects, to testing and deploying to VR headsets, simulators, smartphones, and tablets. Additionally, this XR book takes you on a journey from the basics of Unity and C# to advanced techniques such as building multiplayer applications and incorporating hand- and gaze-tracking capabilities. By the end of this book, you'll be fully equipped to create cutting-edge XR projects for engaging individual, academic, and industrial use cases that captivate your audience.

Adding particles to VR scenes with varying properties

Do you recall the last time you attended a live concert when, at the pinnacle of a legendary song, the stage was enveloped by a blanket of white fog while you were lost in the music with your friends? Taking inspiration from the theatrical smoke often utilized in real-world concerts, we’re going to apply our recently acquired knowledge about Unity’s Particle System to create a similar effect. Our objective is to integrate a particle system into our drum scene to release fog every time a drum is hit, with the intensity of the fog corresponding to the velocity of the strike. The more frequently the drums are played, the more the fog should saturate our scene, and vice versa, thereby fully replicating the euphoric sensation of being at a genuine concert.

To achieve this objective, we need to first initialize a Particle System in our scene.
