摘要
首先对进行处理的规则体数据进行描述,阐述了它采集空间位置的规律,即如何由体数据文件中属性的位置计算出它在空间中的坐标;然后介绍基于这种数据结构的四个步骤对采样点的属性值进行判断、分析即图形绘制以得到用户想要的三雏图形的外包面,其基本思想是将整个体空间分割为多个四面体后,再通过不断的别除得到体外表面;最后是对此项技术在实际应用中的展望。
The paper first introduce what is the regular volume data which then to operate. How to get the vertices from the regular volume data.Then introduce how to get the unique surface triangle extraction through 4 steps which bases on this data struction. The base idea is building all the tetrahedral elements then get some of them out so as to get the surface. Finale discusses the application of this extraction in the future.
