Description

technical field

[0001] The invention relates to the field of information technology, more specifically, it is a three-dimensional dynamic visualization display method for flood evolution numerical simulation results based on WebGL. Background technique

[0002] The use of visualization technology to express various information of flood evolution has become an indispensable part of the field of flood information management. In order to be able to grasp the law of flood evolution more efficiently, many flood information including flood submergence range, water level, and area at different times need to be displayed intuitively. Many commercial organizations and related researchers in China have developed different flood data for different application backgrounds. Visualization system platform.

[0003] At present, the 3D dynamic visualization of flood evolution is mainly based on OpenGL technology, using the C / S architecture (ie Client / Server, client / server structure). With ...
