| 摘 要： | 主要讨论了基于视点地形模型的多分辨率表示机制、动态地形简化算法等问题,通过分析人眼视觉敏锐度模型,将凝视效应、动态视觉加入地形误差评价函数,提出的新算法可以有效地适应虚拟座舱系统的需求.算法在建立人眼模型模拟人眼特性时避开了复杂的生物学特性,视觉评价函数结构简单,计算量小,优化三维引擎同时代入的附加消耗很小.经实验验证算法是有效的.

| Abstract: | Methods for analyzing dynamic multi-resolution terrain models for virtual cockpit systems are discussed.A new model based on the human vision characteristics is presented in order to make better display for terrain rendering,taking into consideration the models of retina gaze and eye motion.It is focused to simplify the 3D engine to avoid complex bio-characteristic of human eyes.The final vision terrain evaluation functions are quite simply with little additional computation cost.Experimental results show the effectiveness of the proposed algorithm. |
