Clouds play an important role for creating realistic images of outdoor scenes. Many methods have been proposed for modeling and rendering clouds. Among these methods, Dobashi et al. proposed a simple but efficient cloud rendering algorithm based on splatting algorithm and take into account single scattering in couds. This algorithm has been used in many papers to generate realistic clouds images. However, in images generated by using Dobashi's method, lattice like artifact can be easily perceived. This paper describes a method to improve the quality of cloud image generated by dobashi method. We perturb the positions of cloud particles and resample the density at perturbed position within neighboring meatballs to remove the regular pattern from regular space lattice structure and adding noise to texture of billboard used in the original method. |
