Influence of Blending Functions on Volumetric Cloud Images
Bogdan Lipu�, Nikola Guid · Journal of Computing and Information Technology · 2007
Various blending functions can be applied in the volumetric modelling of clouds. This paper analyzes the impact of five different blending functions (linear, cubic, Wyvill-1, Wyvill-2, and cosine) on cloud shape, structure, and area. We have found that there are only negligible differences among them. Therefore, we can conclude that the simple linear blending function satisfies all the desired properties for generating cloud images by volumetric modelling.
