In scientific visualization and computer graphics, volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field.

The color rendering of a light source refers to its ability to reveal the colors of various objects faithfully (i.e. to produce illuminant metamerism) in comparison with an ideal or natural light source.

Architectural rendering, architectural illustration, or architectural visualization (often abbreviated to archviz or ArchViz) is the art of creating three-dimensional images or animations showing the attributes of a proposed architectural design.

the process of generating an image from a model by means of computer software.

Separating fat from meat thermally.

A color rendering index is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source.

(computer graphics) An algorithm for determining the visibility of objects in a three-dimensional world, based on partitioning the space into polygonal, generally convex regions that can be used to form generalizations about the visibility of objects within those regions.
