| 摘 要： | 实时优化自适应网格(ROAM)地形绘制算法是目前使用最广泛的网格构造算法之一.在研究和实验的基础上,提出了一种基于视觉特征的ROAM地形简化算法,该算法根据人类的视觉特征,引入视域裁剪和地平线遮挡剔除相结合的方法,进一步简化了ROAM算法渲染的地形模型.实验结果表明,该算法能实时动态地生成地形模型,基于本方法实现的原型程序在普通的PC机上取得了理想的渲染效果.

| Abstract: | Real-time Optimally Adapting Meshes(ROAM) is one of the most widely used algorithms in triangular mesh construction.An ROAM terrain simplification algorithm based on vision character is developed in this study.Vision character is applied and view-of-field culling is integrated with occlusion horizon culling to realize more simplified terrain model.Experimental results show that the algorithm proposed can dynamically generate terrain model in real time and the prototype program using this method produces a s... |
