基于OpenGL技术的通风系统可视化模拟

Visual Simulation of Ventilation System Based on OpenGL Technology

为了提高矿井通风系统的灵活性和开放性,基于OpenGL的三维可视化关键技术提出了三角形拼构法对巷道及内部设施进行建模,三角剖分算法对拼接处的处理,粒子系统对动态风流模拟的技术。该方法实现了巷道拼接等复杂情况的的正确建模,降低巷道模型及拼接算法的复杂度,同时创新地实现了属性数据和风流动态模拟的双向查询。

In order to improve the flexibility and openness of mine ventilation system, the paper proposes that using triangular light constitutive method to build model in roadway and internal facilities, using triangulation algorithm to process splice, using particle system to simulate dynamic air flow based on OpenGL three - dimensional visualization key technology. The method achieves correct modeling of the roadway splice under complex situations, reduces the complexity of roadway model and splicing algorithm, and innovatively achieves bidirectional query of attribute data and air flow dynamic simulation.
