摘要
地表3维景观几何对象经过模型化后,都存储在计算机中,只有将其模型进行可视化,才能看到虚拟模型化后的地物景观。本文主要讨论了利用Creator,采用纹理和贴图技术、LOD模型、动态多分辨率的纹理与影像优化技术,提高3维模型的表达,加强可视化效果。
Geometrical object of earth surface landscape is simulated, and stored in the memory of computer. As long as the models are visualized, the landscape after virtual modeling can be simulated. This paper mainly discusses the technologies of texture and mapping, model of LOD, dynamic multiple resolution texture, and image optimization method to enhance the representation of three - dimension model and effect of visualization.
