Its sooo urgent..plz give me a report on shading language seminar

Shading languages used in offline rendering produce maximum image quality. Material properties are totally abstracted, little programming skill and no hardware knowledge is required. These kind of shaders are often developed by artists to get the right "look", just as texture mapping, lighting and other facets of their work.

Processing such shaders is time-consuming. The computational power required can be expensive because of their ability to produce photorealistic results. Most of the time, production rendering is run on large computer clusters.
