Graphics Algorithms Design for Volumetric 3-D Display
摘要
Abstract
For volumetric 3-D display whose imaging space is created by a spinning double bladed heli-coidal screen with layer-by-layer scan, a graphics software framework is designed and implemented. The core structure consists of voxelization, sliced image rendering and synchronization control. Graphics system obtains volume data by discretizing mesh models in 3-D sample space, then the volumetric dataset of the object is rendered into a stack of sliced images according to helicoid geometry. Through proper synchronization control,the sliced images are projected onto the spinning screen in rapid succession. Finally, the time serie sliced images fuse into a whole 3-D image in true space because of persistence of vision. The software has been tested on a volumetric 3-D display prototype, the 3-D images occupy real physical space, and viewers can watch them directly from almost all directions and change views simply by walking around the display, just as observing real physical object.关键词
