一个基于映射曲面形式的二维网格采样数据场可视化方法

A Visualization Method of the Grid Sampled Data based on Surface-mapping Technology

本文提出了一种基于映射曲面形式的三维可视化方法,较传统的高度场表示所采用的双三次曲面表示法,实现了采样数据点的高精度可视化表现。而且,与同类方法相比,本方法具有灵活性高,能够适于多种应用,并且执行效率高的特点。同时讨论了如何利用OpenGL图象接口的实现问题。在分析了该方法特点的基础上,给出了一个应用实例。

Parametric curve and curved surface become more and more important in computer graphics application. In this paper, a systemic method using openGL technology is presented to tessellate height fields scientific visualization models. Comparing to previous methods, it works well in realtime display application with good visual quality.
