Then , this article analyzes the process of vrml animation , classifies the animation in vrml , which is interpolator animation , viewpoint animation and frame animation , discussing the principles and methods respectively
接着，本文分析了vioal动画的流程，对vrml中的动画进行了分类，即分为插值器动画、视点动画和帧动画，讨论了它们各自的实现原理和方法。
This study choosed arc view gis by way of foundation platform and developed the function modules for region geophysics and geochemistry ( for example hydrological function and background analyst for region geochemistry and transformation for potency field and transformation of map projection and correlation analyst and grid data treating and inserter for kriging and trend and so on ) except using the basic functions of arc view gis ( e . g . neighbour analyst and spatial data treating and surface analyst and model constructor and so on )
本论文选择arcviewgis作为基础平台，除利用arcviewgis的基本功能(如邻域分析、空间数据处理、表面分析、模型构造器等)外，开发了适合于区域地球物理地球化学综合解释的功能模块，如水文功能、区域地球化学背景分析、位场变换、地图投影变换、相关场分析、栅格数据处理、 kriging及trend插值器等。
