Essential Virtual Reality fast: How to Understand the Techniques and Potential of Virtual RealityEssential Virtual Reality fast tells you what is and isn VR! John Vince provides a potted history of Virtual Reality and explains in easy-to-understand terms what computer graphics are and how they are integral to VR systems. You'll see how important it is to understand the part human factors have to play in creating a good VR system (sound, sight, touch and balance) and take a look at a working VR system. You'll get the answers to questions like: - What hardware and software is used? - How does multi-user VR work? - Can you network VR? - What are the applications? - What is the future for VR? And you'll have a far better understanding of the impact these exciting techniques will have on our everyday lives. |
