Virtual Reality with VRTK4: Create Immersive VR Experiences Leveraging Unity3D and Virtual Reality T
Rakesh Baruah
Résumé
You'll start by reviewing spatial computing, an emerging field that encompasses self-driving cars to space exploration. You'll also create your own virtual reality environments for use on headsets such as those from Oculus and HTC. Using the Unity3D game engine and the Virtual Reality Toolkit on a computer or laptop, you will walk through the fundamentals of virtual reality with as little code as possible. That is the beauty of Unity and the Virtual Reality Toolkit. You will discover how to use buttons in a virtual space, gaze-tracking for user input, and physics for enabling interaction between a human and a virtual space.
From game design to education to healthcare to human resources, virtual reality offers new and creative ways to engage users, students, patients, customers, and more. Not a coding book, Virtual Reality with VRTK4 shows that you don't need to be a computer or graphics whiz to begin creating your own virtual reality experiences.
