一种基于不规则三角网的地层等值线绘制方法
A STRATIGRAPHIC CONTOUR DRAWING METHOD BASED ON TRIANGULATED IRREGULAR NETWORK
摘要
Abstract
Contour maps are the most commonly used geographic features in cartography and are the most basic and common data representation of geological resource information system.According to the characteristics of the geological model of strata visualization,this paper studied and analyzed the shortcomings of the traditional contour tracing methods,and proposed a contour tracing algorithm based on triangulation irregular network.Combined with the practical requirements,this paper simplified the data storage model and achieved the algorithm of contour tracing in VC ++ and OpenSceneGraph development environment.The contour map was filled through the establishment of the mapping rules of the formation attribute,achieving the real effect of 3D visualization of the formation.Based on the stratum data of oil production plant,the feasibility and correctness of the contour tracking algorithm were verified.关键词
