Rendering (computer Graphics) - Academic Core

Academic Core

The implementation of a realistic renderer always has some basic element of physical simulation or emulation — some computation which resembles or abstracts a real physical process.

The term "physically based" indicates the use of physical models and approximations that are more general and widely accepted outside rendering. A particular set of related techniques have gradually become established in the rendering community.

The basic concepts are moderately straightforward, but intractable to calculate; and a single elegant algorithm or approach has been elusive for more general purpose renderers. In order to meet demands of robustness, accuracy and practicality, an implementation will be a complex combination of different techniques.

Rendering research is concerned with both the adaptation of scientific models and their efficient application.

Famous quotes containing the words academic and/or core:

    The academic expectations for a child just beginning school are minimal. You want your child to come to preschool feeling happy, reasonably secure, and eager to explore and learn.
    Bettye M. Caldwell (20th century)

    Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today—but the core of science fiction, its essence ... has become crucial to our salvation if we are to be saved at all.
    Isaac Asimov (1920–1992)
