三维真实感的图形技术是科学计算可视化,电脑动画和三维地理信息系统的核心。Java 3D是一个基于Java技术实现的跨平台的三维可视化编程接口。本文讨论了如何利用Java 3D技术实现具有真实感的地形显示。包括了按照高度值进行分层设色的渲染技术和实现以正射影像为基础的纹理技术。最后讨论了如何利用Java的Web支持把程序移植到Internet上,实现真实感地形在Internet上发布的方法。
Three-dimensional photorealistic graphics technology is at the core of scientific computing visualization, computer animation and three-dimensional geographic information systems. Java 3D is a cross-platform, three-dimensional visual programming interface based on Java technology. This article discusses how to use Java 3D technology to achieve a realistic topographic display. Including the rendering of layered color-by-height values and texture technology based on orthophoto. Finally, it discusses how to use Java’s Web support to transplant the program to the Internet and realize the realistic terrain publishing method on the Internet.
