Rendering Algorithm of the Sky Illumination Based on GPU

Abstract:

This paper proposed the algorithm of the sky color rendering based on the relationship between the height of viewpoint and the altitude of scattering point with atmospheric density after the study of atmospheric absorption and scattering and sky illumination simulation methods. The geometrical model of the sky dome and rotation and the sun location is presented. The rendering method based on GPU is designed. The results of experiment show that the rendering effect of the sky illumination based on this algorithm is realism.
