bidirectional reflection distribution

bidirectional reflection distribution A reflectance model for producing realistic images of rough surfaces by means of computer graphics developed by Robert Cook in 1981. Reflectance models describe both the color and the spatial distribution of reflected light. The bidirectional reflection model predicts the directional distribution and spectral composition of the reflected light. This is split into two components that represent the light reflected from the surface of the material and a diffuse component that is dependent on the nature of the surface. Bidirectional reflection distribution was one of the first models to render images that could look plastic or metallic depending on the parameters of the surface.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
