摘要/Abstract

摘要：

为了解决形象化模型显示方法硬件依赖性过高、不易实现推广等问题，从“分队指挥模拟对抗演练系统”虚拟战斗人员显示的实际需要出发，提出了一种基于纹理切换的虚拟战斗人员三维显示方法. 重点叙述了这种纹理切换显示方法的基本思路、算法思想、技术路线以及具体实现；并且对实现过程中涉及到的在视点角度发生变化的条件下，如何同时保持纹理框架朝向不变以及如何保持虚拟战斗人员逻辑方向不变两个纹理切换的关键问题进行了重点研究.

关键词: 虚拟战场环境, 纹理切换, 虚拟战斗人员, 面向对象开发

Abstract:

In order to solve the problems that 3D display methods of virtual soldiers vivid model is heavily dependent on expensive hardware and difficult to realize and popularize, the 3D display methods based on textureswitch are presented according to the actual need of 3D display of virtual soldiers in the case of “unit commanding simulated confrontation training system”. The basic ideas, algorithms ideological, technical routes to achieve, and the realization of algorithms are described in details. Moreover, the two key issues, that how to keep texture framework always against the screen and the logic orientation of virtual soldiers when the viewpoint is changing, have been demonstrated.

Key words: virtual battlefield environment, textureswitch visualization, virtual soldiers, object－oriented programming
