三维地形建模与可视化研究

Study on 3D Terrain and Visualization

针对当前地形三维可视化及其绘制技术的研究现状,在吸取计算机图形学、科学计算可视化、虚拟现实、计算机网络的先进理论和技术成果的基础上,围绕数字地形模型以及基于网络的三维地形可视化等核心技术内容展开研究,提出了建立数字地形模型中不规则三角网(TIN)的改进算法和思路,给出了运用VC++和OpenGL实现的三维真实感地形可视化实验软件。

Aiming to the theoretical and methodological studies in the 3D terrain rendering, in the base of some interdisplines, such as 3D computer graphics, scientific computation visualization, virtual reality, and computer network, an optimal algorithm was designed to create a Delaunay TIN with constraint of feature lines. Based on VRML, a 3D workout software was given using VC + + and OpenGL.
