Samenvatting
Virtual reality has long been the domain of researchers and developers with access to specialized hardware and proprietary tools. With the appearance of the Oculus Rift VR headset, the game has changed. Using standard programming tools and the intuitive Oculus SDKs, you can deliver powerful immersive games, simulations, and other virtual experiences that finally nail the feeling of being in the middle of the action.
'Oculus Rift in Action' teaches you how to create 3D games and other virtual reality experiences for the Oculus Rift. You’ll explore the Rift hardware through examples of real applications using the Oculus SDK and both the Oculus C API and the Unity 3D graphics engine. Along the way, you’ll get practical guidance on how to use the Rift’s sensors to produce fluid VR experiences.
What's inside
Creating immersive VR experiences
- Integrating the Rift with the Unity3D SDK
- Implementing the mathematics of 3D
- Avoiding motion-sickness triggers
Experience with C++, C#, or another OO language is assumed.
