Solid Modelling
The ability to define solid models as collections of surfaces and combine them using the set operations intersection, union and difference.
Level of Detail
The ability to specify several definitions of the same model and have one selected based on the estimated screen size of the model
Motion Blur
The ability to process moving primitives and anti-alias them in time
Depth of Field
The ability to simulate focusing at different depths
Programmable Shading
The ability to perform shading calculations using user-supplied RenderMan Shading Language programs
Special Camera Projections
The ability to perform nonstandard camera projections such as spherical or Omnimax projections
Deformations
The ability to handle nonlinear transformations such as bends and twists
Spectral Colors
The ability to calculate colors with an arbitrary number of spectral color samples.
Texture Mapping
The ability to index a texture map with the surface's texture coordinates
Environment Mapping
The ability to model the environmental illumination by indexing a texture map with a direction vector
Bump Mapping
The ability to perturb just surface normals by giving a displacement map
Shadow Depth Mapping
The ability to index a shadow map with a position
Volume Shading
The ability to attach and evaluate volumetric shading procedures
Ray Tracing
The ability to evaluate global illumination models using ray tracing
Global Illumination
The ability to evaluate indirect illumination models using radiosity or other global illumination techniques
What are parameters in the global state referred to as? (remains constant while rendering a single image or frame of sequence)
Options (camera and display parameters, quality or type of rendering (global level of detail, number of color samples, etc))
What are parameters in the current state referred to as? (changes from geometric primitive to geometric primitive)
Attributes (controls appearance or shading (color, opacity, surface shading model, light sources, etc))
