BYO3D 2011: Welcome
May 17, 2015
Driven by the recent resurgence of 3D cinema, depth cameras and stereoscopic displays are becoming commonplace in the consumer market. Introduced last October, Microsoft Kinect has already fostered gesture-based interaction for applications well beyond the intended Xbox 360 platform. Similarly, consumer electronics manufacturers have begun selling stereoscopic displays and inexpensive stereoscopic cameras. Most commercial 3D displays continue to require cumbersome eyewear, but inexpensive, glasses-free 3D displays are imminent with the release of the Nintendo 3DS.
At SIGGRAPH 2010, the Build Your Own 3D Display course demonstrated how to construct both LCD shutter glasses and glasses-free lenticular screens, providing Matlab-based code for batch encoding of 3D imagery. This follow-up course focuses more narrowly on glasses-free displays, describing in greater detail the practical aspects of real-time, OpenGL-based encoding for such multi-view, spatially multiplexed displays.
The course reviews historical and perceptual aspects, emphasizing the goal of achieving disparity, motion parallax, accommodation, and convergence cues without glasses. It summarizes state-of-the-art methods and areas of active research. And it provides a step-by-step tutorial on how to construct a lenticular display. The course concludes with an extended question-and-answer session, during which prototype hardware is available for inspection.
