Abstract


Clouds are complex objects with undefined and varying shapes and structures. They have fractal surfaces of various density and transparency levels. Physical properties of cloud such as shape, colour and area of expanse and height of occurrence determine the type of the cloud. Rendering a real-time 3D cloud object on a two dimensional screen is considered to be a tedious task, while having a good scope of research in the field of Computer graphics. The rendering needs high speed graphics hardware which gives greater performance and optimal accuracy. while listing some crucial physical properties of a cloud which directly or indirectly affect the appearance of the cloud, this communication gives a short note on a three step 3D cloud rendering process, i.e., cloud modeling, multiple scattering and cloud rendering.
