Renderman discussed

The two basic terminologies in the arena of computer graphics are “modeling” and “rendering”. The render man serves the purpose of a good interface between modeling and rendering. Renderman, more specifically known as renderman interface specification was introduced by Pixer Animation Studios.

Broadly speaking, the primary objective of renderman is that, it defines a three dimensional scenario and provides a realistic image of that. This particular application is extensively used in computers, video games, televisions, photography etc.

The relevance of renderman is well conveyed when knowing, that this technology has been adopted by Hollywood movies to impart high quality and immaculate visual display.

The success of renderman in computer graphics owes a lot to its capability to support geometric shapes of high level such as cubes as a primitive shape. The introduction of “shading language” by renderman also was a revolution in that field.

Importance of shading language:

Definitions of the surfaces that are to be constructed using renderman, are done with the supreme assistance of procedure oriented programming language, C. That means, all the actions in construction are written or defined in procedures, which is a revelation of the shading language.

A magnified impact of this application is understood, when knowing that other applications concentrate in changing a set of attributes to define the material surfaces. Apart from this, movement of the object, lighting of the object, shading etc. are made possible by the shading language.

A successful rendering implies the image to have both orthographic and perspective (terminologies of computer graphics, both implies different views of an object) views. The resolutions of the picture should be according to the user’s requirement and should be able to afford different color combinations.

It should be able to perform shading calculations and should map the texture maps and environment maps.

It should be noted that, Open GL or Open Graphics Library and renderman has a lot of similarities. Job opportunities are in surplus in this area, and are the best tool to develop high quality images and video.
