The rendering equation describes the total amount of light emitted from a point x along a particular viewing direction, given a function for incoming light and a Bidirectional reflectance distribution function | BRDF.

The Bidirectional Texture Function ( BTF ) is appropriate for modeling non-flat surfaces, and has the same parameterization as the SVBRDF ; however in contrast, the BTF includes non-local scattering effects like shadowing, masking, interreflections or subsurface scattering.

Bidirectional script support is the capability of a computer system to correctly display bi-directional text.

Some of the most used methods are Path Tracing, Bidirectional Path Tracing, or Metropolis light transport, but also semi realistic methods are in use, like Whitted Style Ray Tracing, or hybrids.

Bidirectional texture function ( BTF ) is a 7-dimensional function depending on planar texture coordinates ( x, y ) as well as on view and illumination spherical angles.

* Bidirectional PIM explicitly builds shared bi-directional trees.

* Bidirectional paper motion was similarly servo-controlled allowing quick printing of subscripts and superscripts as well as fast slewing past white space.

Researchers at CRULP also actively participate in national and international bodies, including PTCL R & D Fund, Urdu Computing Standardization Committee of National Language Authority, Editorial Board of Localization Focus published by Localization Research Centre at University of Limerick in Ireland, and Unicode ’ s Bidirectional Committee List.

Bidirectional signalling was also provided on the double-track sections between Pakenham and Bunyip, and between Longwarry and Moe.

Bidirectional signalling through the EPH-family receptor Nuk and its transmembrane ligands.

The Spatially Varying Bidirectional Reflectance Distribution Function ( SVBRDF ) is a 6-dimensional function,, where describes a 2D location over an object's surface.

The Bidirectional Surface Scattering Reflectance Distribution Function ( BSSRDF ), is a further generalized 8-dimensional function in which light entering the surface may scatter internally and exit at another location.

* Scripts ( artificial intelligence ), a structure for representing procedural knowledge

Scripts similar in appearance to this writing system include those for Ugaritic and Old Persian.

Scripts existed for the film as early as 1976 under titles such as The Cut-Whore Killings and The William Munny Killings but Eastwood delayed the project because he wanted to wait until he was old enough to play his character and to savor it as the last of his western films.

Scripts were also written for a proposed television series involving both Tom Swift Jr. and his father, the hero of the original book series.

Scripts were associated with objects in HyperCard files ( so-called " stacks "), and HyperTalk allowed manipulating these objects in various ways, changing their properties using the " set " command, for example.

The Hitchhiker's Guide to the Galaxy: The Original Radio Scripts is a book, published in 1985, containing the scripts for the original radio series version of The Hitchhiker's Guide to the Galaxy by Douglas Adams.

( Sykes and Milligan later jointly formed Associated London Scripts ( ALS ) with Ray Galton and Alan Simpson, a writers ' agency which lasted for well over a decade until being effectively dissolved in 1967.

Rules for Han unification are given in the East Asian Scripts chapter of the various versions of the Unicode Standard ( Chapter 12 in Unicode 6. 0 ).

According to Merrill, the spirits ordered him to write and publish the next two installments, Mirabell: Books of Number in 1978 ( which won the National Book Award for Poetry ) and Scripts for the Pageant in 1980.

Scripts and storyboards were prepared in both English and Japanese and with a fast turnaround in the production process, the episodes were delivered to Zavala-Riss Productions in the US for English dubbing ( the unit that also dubbed Speed Racer, featuring the same voice actor cast ).

Scripts for the final sixth season did not hit the campy lows of the previous two years and reestablished a bit of the seriousness of the show, often with science fiction elements like a Kryptonite-powered robot ( a left-over prop from " The Bowery Boys Meet the Monsters "), atomic explosions, and impregnable metal cubes.

The complete scripts for the series have been published as Rising Damp: The Complete Scripts by Eric Chappell ; edited by Richard Webber.

Scripts were written for five issues and three issues were penciled, though Marvel was not granted the Micronauts license by the copyright holder, Abrams / Gentile Entertainment, forcing the series to be canceled.

Scripts for this and other sequels circulated, and the original film's director, Joel Schumacher, made several attempts at a sequel during the 1990s.

Scripts for later seasons have not yet been published as of 2010, though 2005-2009 lead writer Russell T Davies has made his scripts available online.

XBMC features a Python Scripts Engine for addon extensions, WindowXML application framework ( a XML-based widget toolkit for creating a GUI for apps / widgets ) in a similar fashion to Apple Mac OS X Dashboard Widgets and Microsoft Gadgets.

Scripts and extensions Free and paid for pre-written scripts are available from the Vegas community on the web.
