Research of Air Pollution Dispersion Visualization Based on GPU and Volume Rendering
Lei Wang · Advanced materials research · 2013
To address the air pollution diffusing problem, a visualization algorithm based on fluid diffusion physical model and volume rendering is proposed to simulate the diffusion process epically for the urgent pollution accidents. The diffusion model is based on the simplified heat diffusion equation and the basic vortex constraint. The texture mapping based volume rendering method is adapted to handle the visualization algorithm. In addition, the render process adopts the GPU to implement the real-time visualization rendering.
