Three-dimensional environment air quality dynamic rendering method

Abstract

The invention discloses a three-dimensional environment air quality dynamic rendering method, and belongs to the technical field of image processing. The method comprises the following steps of modeling the meteorological mode result data into a three-dimensional space grid field, forming a cubic space containing texture slices through a texture mapping mode, adopting a projection line technology, according to a certain strategy, fusing and accumulating the color value of each slice sampling point, forming a final pixel point color, and rendering the overall three-dimensional field effect, so that the technical problem that the simulation change effect of particle clusters is achieved by changing the color and transparency of textures and in a particle and texture manner, so that the three-dimensional air quality mode result data changing at multiple moments is drawn at a webpage end, is solved. According to the present invention, the rendering effect is three-dimensional, the emphasis on a threshold interval can be artificially highlighted, and the multi-moment data can be loaded according to a dynamic change effect; and the GPU can be used at the webpage end through a shader acceleration rendering method.

Description

technical field [0001] The invention belongs to the technical field of image processing and relates to a dynamic rendering method of three-dimensional ambient air quality. Background technique [0002] 3D particle system rendering technology is an important part in the field of computer simulation.

Problems solved by technology

[0004] 1. Use the result data to perform simulations in the form of static pictures covering data points based on location information, which lacks intuition

[0005] 2. Most simulations are mainly rendered by establishing physical models, distribution models, and carrier models of relevant elements. The final rendering results are random and cannot fit the real data results

[0006] 3. The traditional 3D particle system rendering technology is based on background computing. Although the computing efficiency has been improved to a certain extent, there are still problems in portability, simplicity, and cross-platform operation.

[0007] 4. In addition to the above problems of intuition, authenticity and p...
