基于OpengL的面向对象的巷道三维可视化

OpengL based object-oriented visualization of Roadway

介绍了巷道三维模型建立的过程,即巷道数据处理、巷道三维实体模型、模型OpengL映射、三维场景设置、坐标投影变换、巷道三维显示。采用面向对象的VC++的结构体数据类型和类建立描述组成巷道中心线的不同基本元素空间信息的数据结构。利用OpenGL原语进行描述,对巷道实体三维数学建模。通过三维场景设置,控制三维巷道的生成效果,运用OpenGL的Z缓存自动消隐功能构建和生成具有真实感的三维巷道模型,并实现交互式查询。以此解决方案对地下巷道的实际情况进行直观和形象的模拟,对煤矿的信息化管理能力有一定的提高,利于指导煤矿的实际生产。

Introduced the three-dimensional model tunnel process,that is,data processing roadway,roadway three-dimensional solid model,model OpengL mapping,three-dimensional scene set,coordinate transformation,three-dimensional display tunnel.Object-oriented VC ＋ ＋ in the structure data type and class of roadway constructed to describe the composition of the center line of the basic elements of spatial information in different data structures.Using OpenGL primitives to describe the three-dimensional mathematical modeling of the roadway entities.By three-dimensional scene settings,control the formation of three-dimensional tunnel effect,the use of OpenGL＇s Z cache automatically build and generate a blanking feature realistic three-dimensional tunnel model,and implement interactive query.This solution to the underground tunnel of the actual situation and the image of the visual simulation,information management in coal mines have some capacity to improve,which will help guide the actual production of coal.
