数字展馆场景虚拟构建过程中经常出现渲染不畅、场景模型失真等问题,对此将虚拟现实技术应用于场景表面重建实践.基于Delaunay算法构建场景表面格网,结合边折叠方法精简三角形格网的数量;改进传统递归遍历四叉树算法的渲染策略,使用循环结构的四叉树算法由上至下按顺序地生成全部四叉树节点,高质量实现LOD技术,完成数字展馆场景表面模型渲染.测试结果显示,该方法重建的数字展馆场景表面三角格网较为均匀、占用内存量小,表面渲染流畅度高,呈现高质量的数字展馆场景建模效果.
Practical Application of Virtual Reality in Surface Reconstruction of Digital Exhibition Halls
During the virtual construction process of digital exhibition halls,there are often problems such as poor rendering and distorted scene models.Therefore,virtual reality technology is applied to the practice of scene surface reconstruction.Construct a scene surface grid based on Delaunay algorithm,and combine edge folding method to reduce the number of triangular grids;improve the rendering strategy of the traditional recur-sive traversal Quad tree algorithm,use the cyclic Quad tree algorithm to generate all Quad tree nodes in order from top to bottom,and achieve high-quality LOD technology to complete the rendering of the digital pavilion scene surface model.The test results show that the surface triangular grid of the digital exhibition halls scene re-constructed by this method is relatively uniform,occupies less memory,and has high smoothness in surface ren-dering,presenting high-quality digital exhibition hall scene modeling effects.
