【摘要】 传统体育馆售票方式无法使购票者在购票时实时感知座位的具体视角。本文提出一种解决思路,其基本思想是根据设计图纸提取场馆的拓扑结构和几何信息,并对场馆三维建模,虚拟仿真体育馆内部场景,再使用OpenGL库函数将模型导入系统来实现场景旋转、转换和购票等人机交互操作。为使用户在购票时更好地感受逼真的三维视角效果,运用画法几何中射线和三角形求交算法解决三维仿真交互中座位定位等问题。更多还原

【Abstract】 The traditional way of ticket-selling can not make buyers perceive the concrete perspective of the seat in real time when buying tickets.In this paper,we propose a solution,the basic idea is according to the design drawings,extracting the topology and geometry information of the stadium,and accomplishing three-dimensional modeling of venues,virtually simulating the inner scene of the gym,then using OpenGL graphics library to import external model into the system to achieve scene rotation,conversion,ticketing and other man-machine interaction.In order to allow users to feel vivid 3Dperspective better when buying tickets,we use ray and triangle intersection algorithm based on descriptive geometry to solve the problems of three-dimensional simulation and interaction in seat positioning.更多还原
