基于映射理论的曲面雕塑技术

THE SURFACE SCUPlUKING TECHNIOUE EASED ON THE MAPPING THEORY

本文描述了一种建立在映射基础上的曲面雕塑技术，给出了相应的理论推导和实验图形。任意曲面的雕塑造型一直是图形学中的一个难，久，这里提出的映射方法易于实现，且保持曲面原有的几何属性及其数学上的严密性，这种数据场的映射造型技术可以实现许多复杂的形体造型，如古董、艺术、人体模型等等，更重要的是通过这种数据场变化对形体的作用及其运动过程的控制或显示起到很好的效果。

This paper describeS the surface scupturing techmque whiCh is based on the mappingtheory,and demonstrate the formula deducing procedure as well as the experiment graphics。It is a hard point for the scupturing rnodeling of any free form surface,Here the method ofthe mapping is very easy to make,and perserve the geornetric attributes and the mathematicalstriction,This mapping modeling technique based on the data fields may realize many com-plex objects modeling,such as antiques,arts,human bodies as well.We may view or changethe objects graphics by adjusting the mapping data fields.
