Fast algorithm for cloud rendering using flat „3D textures”

Abstract

This paper presents an efficient method to render clouds in their natural dynamic (i.e.forming, dissipating, flowing). The algorithm uses flat „3D textures” to represent volumetric data. This is used to compute the amount of light reaching each voxel. The light values are computed in real time and then visualised using a slicing technique to enable on-line interaction with the cloud model.
