VEA 2012: Natural exploration of 3D massive models on large-scale light field displays using the FOX proximal navigation technique

摘要: We report on a virtual environment for natural immersive exploration of extremely detailed surface models multi-projector light field displays, which give multiple, freely moving, naked-eye viewers the illusion seeing and manipulating 3D objects with continuous horizontal parallax. Our specialized user interface, dubbed FOX (Focus Sliding Surface), allows inexperienced users to inspect at various scales, integrating panning, rotating, zooming controls into single low-degree-of-freedom operation. At same time, takes account requirements comfortable viewing display hardware, has limited field-of-view variable spatial resolution. Specialized multi-resolution structures, embedding fine-grained, per-patch index within coarse-grained patch-based mesh structure, are exploited fast batched I/O, GPU-accelerated rendering, user-interaction-system-related geometric queries. The capabilities system demonstrated by interactive inspection giga-triangle dataset large-scale, 35MPixel controlled wired or vision-based devices. Results thorough evaluation, involving quantitative subjective measurements, discussed.
