Abstract

The invention discloses a method for constructing real-time visual fluid in a complex three-dimensional pipe network, which comprises the following steps of: analyzing and concluding various pipelinesand intersections in the complex three-dimensional pipe network, obtaining pipe network center line data through pipe network modeling and center line acquisition, and determining the types of the pipelines and the intersections; For various pipelines and intersections, methods of intersection operation, pipe network bottom surface reconstruction and the like are adopted to establish a fluid surface model so as to reduce the real-time fluid modeling calculation amount. The fluid surface and the fluid depth are updated in real time based on real-time fluid depth information obtained through asensor network or numerical simulation and the pipe network model category, and real-time fluid modeling is achieved; And finally realizing real-time visualization of the fluid under the complex three-dimensional pipe network scene by adopting a rendering technology. Taking mine water inrush as an example, the feasibility of the method is verified, and visual analysis is carried out. The problem that real-time visualization of fluid in a complex three-dimensional pipe network is difficult to achieve is solved.

technical field [0001] The invention relates to a real-time fluid visualization technology in a complex three-dimensional pipe network, in particular to a method for constructing a real-time visualized fluid in a complex three-dimensional pipe network. Background technique [0002] Complex three-dimensional pipeline network is an important infrastructure in the survival and development of cities, such as common oil and gas pipelines, mine tunnels, urban subway tracks, underground water pipelines, etc., are closely related to people's daily life and work. Real-time simulation of the fluid movement state in the three-dimensional pipe network can effectively help people monitor the material transportation state in the pipe network, and guide people to avoid risks in time during disaster prevention and avoidance (such as water inrush from roadways and tracks); Fluid simulation can effectively simulate underground underground rivers and surface rivers in 3D geological simulation;...

AI Technical Summary

Problems solved by technology

In a large-scale complex three-dimensional pipe network scene, due to the vertical three-dimensional distribution of the pipe network and the narrow internal space of many branch paths, the fluid in the pipe network is scattered and not distributed on the same plane, and the boundary problem with the pipe network must be paid attention to everywhere. If traditional fluid modeling methods such as particles or physics are used, a large amount of computational modeling is required at all times, and real-time fluid simulation cannot be completed even with GPU parallel computing acceleration
