摘要
通过分析了态势符号的表达方式和特点,提出了一种基于模板阴影体技术的实时绘制复杂态势符号的方法,实现在三维场景中的高质量叠加显示态势符号,达到随地形起伏的目的。实验证明,该方法能用于在三维场景中绘制复杂态势符号,并在系统项目中取得很好效果,使绘制的态势符号能随地形起伏。
In this paper, we analyse the expression mode and character of situation symbol are analyzed, and a new rendering method of complex situation symbol over 3D terrain is preserted based on the stencil shadow volume technique, expecting the objective of hypsography. Experiment has proved the method can be used to render complex situation symbol over 3D Ter rain and acquire good effect in sytem item.
