This paper presents a new method for realistic real-time rendering of air pollutants based on image processing. The air pollutants' variable density can create many shapes of mist what can add a realistic environment to virtual scene. In order to achieve a realistic effect, we further enhance thus obtained air pollution data getting from monitor in spatial domain. In the proposed method we map the densities of air pollutants to different gray levels, and visualize them by blending those graydoi:10.5815/ijitcs.2011.05.05 fatcat:ajczoy277nc6zexy647z4zlafe
