三维数据场在扫描式体显示器中的可视化
Visualization of 3D Datasets Based on Swept-Volume Display
摘要
Abstract
Based on double-helicoid swept-volume display system, this paper proposes and implements a 3D datasets volume visualization scheme in real stereoscopic space. Homogenous image space is created by the screen's rotational scanning. In rendering process, 3D regular discrete data is subdivided into a series of helicoid slices evenly. Then each data slice is rendered into an image frame separately. The rendered images are projected into the imaging space in rapid succession through a high-speed projector. By using multi-thread technique, synchronization between projected images sequence and screen's rotation is achieved. Finally the whole spatial image is scanned out layer by layer. The experimental results show that elements of the presented spatial images are uniformly distributed and well defined. All three dimensionalities of the images are reserved inherently; this approach offers omni-direc-tional viewing freedom around the display.关键词
