Imager shaders describe a color transformation to final pixel values.

Volume shaders manipulate the color of a light as it passes through a volume.

Only one RenderMan implementation, the AIR renderer by SiTex Graphics, implemented this shader type, supporting only a single linear transformation applied to the space (this was more like a Transformation shader, if such a type existed).

Deformation shaders transform the entire space of a geometry.

Displacement shaders manipulate surface geometry independent of color.

They output the final color and position of the point by considering the incoming light and the object's physical properties.

Surface shaders model the optical properties of an illuminated object.

Light source shaders compute the color of the light emitted from a point on the light source towards a point on the target surface.

The language defines six major shader types: It is also one of the first shading languages ever implemented. The RenderMan Shading Language (often referenced as RSL or SL, for short), which is defined in the RenderMan Interface Specification is the most common shading language for production-quality rendering. Most of the time, production rendering is run on large computer clusters. The computational power required can be expensive because of their ability to produce photorealistic results.

Processing such shaders is time-consuming. 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. Material properties are totally abstracted, little programming skill and no hardware knowledge is required.
