摘要
Now the image display techniques have made great progress. The planar display and a fully new true 3-D volumetric display technique are rapidly researched and come into the application. A method based on the voxel makes the observer able to get a true 3-D effect freely without any additional facilities. This paper introduces the basic form of the swept-volume display technique and discusses its voxelization process. By the translational motion prototype, this paper emphasizes how to get the voxel mapping matrix. The translated image data are the data of the beam source deflections. Finally the voxel ordering and the optimizing are also discussed.
目前 ,图像显示技术已经不局限于平面显示 ,一种全新的真三维立体显示技术正在迅速发展 ,并逐步走向应用。该技术是完全基于体素的显示方法 ,使得观察者自由地、不需要辅助设备地获得真三维的图像效果。本文重点介绍了该显示技术中的基于动态体技术的基本形式 ,讨论了该技术中所采用的体素化过程。另外 ,通过采用平面直线运动模型 ,重点分析了该模型中的体数据转换矩阵的计算。转换后的图象数据是基于激光束的偏转数据。在该数据基础上 ,还分析了体素的重新排序和优化过程。
