摘要
为解决复杂三维管网中难以实现流体实时可视化的问题,对复杂三维管网内各类管线和路口进行分析和归纳,提出了一种复杂三维管网中流体实时可视化算法。通过管网建模及中线获取得到管网中线数据,并确定管线和路口类型;针对各类管线和路口分别采用求交运算、管网底面重构等方法建立流体表面模型,以减少实时流体建模计算量。基于由传感器网络或数值模拟得到的实时流体深度信息与管网模型类别实时更新流体表面和流体深度,实现实时流体建模;采用渲染技术最终实现复杂三维管网场景下的流体实时可视化。以矿井突水为实例,验证算法可行性并进行可视化分析。
To solve the problem of real-time visualization of fluid in complex 3D pipe networks,the various pipelines and intersections in complex 3D pipe networks are analyzed and generalized,and an algorithm for real-time visualization of fluid in complex 3D pipe networks is proposed.The centerline data of pipeline network is obtained through pipe networks modeling and centerline acquiring,and the types of pipelines and intersections are determined.The fluid surface model is established by the intersection operation and reconstruction of the undersurface of the pipe networks for various pipelines and intersections to decrease the computational load of real-time fluid modeling.The real-time fluid modeling is realized by real-time updating of the fluid surface and fluid depth based on real-time fluid depth information and categories of pipe networks model obtained by sensor networks or numerical simulation;real-time visualization of fluid in complex 3D pipe networks is finally realized by rendering technology.Taking the mine water inrush as an example,the algorithm is analyzed and verified to be feasible.
