【摘要】 地质环境是一个复杂的三维空间信息系统,其信息分析与显示表达迫切需要相应的三维、多维方法。以ArcEngine为基本平台,基于AtiveX技术,采用不规则三角网插值算法、色彩模型,并以OpenGL为技术支撑,并根据地质环境专业特点,构建三维静态、动态演化模型和三维剖面模型。利用ActiveX技术进行模块组件封装,增进程序代码的利用效率和可移植性。更多还原

【Abstract】 Geological environment is a complicated 3D spatial information system,of which the information analysis and display require 3D and multidimensional means correspondingly.According to the professional characteristics of the geological environment,it has constructed the 3-D static model,the dynamic evolution model and the 3-D sectioning model based on ArcObject,truss of AtiveX,the anomalous triangle-mesh inter-polational arithmetic and colorific model and technique of OpenGL.It has encapsulated the modular discreteness by using the technique of ActiveX.It also has furthered the available efficiency and transplantable capability of the process codes.更多还原
