Scene Description Language
A scene description language is any description language used to describe a scene to a 3D renderer, such as a ray tracer. The scene is written in a text editor (which may include syntax highlighting), as opposed to being modeled in a graphical way, but a 3D modelling program may allow for a scene to be exported to a specified scene description language. Some scene description languages may include variables, constants, conditional statements, and while and for loops. For example, 3DMLW and X3D are XML-based scene description languages; YafaRay also employs an XML-based language. Tao Presentations uses XL as a dynamic document description language. POV-Ray has its own Turing-complete language. Examples POV-Ray #declare the_angle = 0; #while (the_angle locally color_hsv 20 * N, 0.3, 1 translate 300*cos(N*0.1+time), 300*sin(N*0.17+time), 500*sin(N*0.23+time) sphere 50 zero N -> if N < 10 then "0" & text N else text N ...

Interface Description Language
interface description language or interface definition language (IDL), is a generic term for a language that lets a program or object written in one language communicate with another program written in an unknown language. IDLs describe an interface in a Language-independent specification, language-independent way, enabling communication between software components that do not share one language, for example, between those written in C++ and those written in Java (programming language), Java. IDLs are commonly used in remote procedure call software. In these cases the machines at either end of the ''link'' may be using different operating systems and computer languages. IDLs offer a bridge between the two different systems. Software systems based on IDLs include Sun Microsystems, Sun's ONC RPC, The Open Group's Distributed Computing Environment, IBM's System Object Model, the Object Management Group's CORBA (which implements OMG IDL, an IDL based on DCE/RPC) and Data Distributio ...

YafaRay
YafaRay (formerly YafRay) is a free and open-source ray tracing program that uses an XML scene description language. There is a YafaRay addon for Blender 2.78. The ray tracer is licensed under the GNU Lesser General Public License (LGPL). History YafaRay's predecessor, YafRay ("Yet Another Free Raytracer"), was written by Alejandro Conty Estévez, and was first released in July 2002. The last version of that program was 0.0.9, which was released in 2006. Due to limitations of the original software design, the YafRay raytracer was completely rewritten by Mathias Wein. The first stable version of the new raytracer, given the name ''YafaRay'' 0.1.0, was released in October 2008. The latest stable version is 3.4.1 released in 2020. Features Rendering ;Global illumination :YafaRay employs global illumination using Montecarlo-derived approximations to produce realistically lit renders of 3D scenes. ;Skydome illumination :The illumination system is based mainly on light coming from ...

3D Computer Graphics
3D computer graphics, or “3D graphics,” sometimes called CGI, 3D-CGI or three-dimensional computer graphics are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an animation) or displayed in real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which typically use completely different methods and formats for creation and rendering. 3D computer graphics rely on many of the same algorithms as 2D computer vector gr ...

VRML
VRML (Virtual Reality Modeling Language, pronounced ''vermal'' or by its initials, originally—before 1995—known as the Virtual Reality Markup Language) is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. It has been superseded by X3D. WRL file format VRML is a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color, UV-mapped textures, shininess, transparency, and so on. URLs can be associated with graphical components so that a web browser might fetch a webpage or a new VRML file from the Internet when the user clicks on the specific graphical component. Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. A special Script Node allows the addition of program code (e.g., written in Java or ECMAScript) to a VRML file. VRML ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of 3D Graphics File Formats
This is a list of file formats used by computers, organized by type. Filename extension it is usually noted in parentheses if they differ from the file format name or abbreviation. Many operating systems do not limit filenames to one extension shorter than 4 characters, as was common with some operating systems that supported the File Allocation Table (FAT) file system. Examples of operating systems that do not impose this limit include Unix-like systems, and Microsoft Windows NT, 95- 98, and ME which have no three character limit on extensions for 32-bit or 64-bit applications on file systems other than pre-Windows 95 and Windows NT 3.5 versions of the FAT file system. Some filenames are given extensions longer than three characters. While MS-DOS and NT always treat the suffix after the last period in a file's name as its extension, in UNIX-like systems, the final period does not necessarily mean that the text after the last period is the file's extension.

Tao Presentations Real-time 3D Rendering Of A Scene Described Using Its Document Description Language
''Tao'' or ''Dao'' is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other philosophy or religion that aligns to this principle. This intuitive knowing of life cannot be grasped as a concept. Rather, it is known through actual living experience of one's everyday being. Its name, ''Tao'' or ''Dao'' , came from Chinese, where it signifies the way, path, route, road, or sometimes more loosely doctrine, principle, or holistic belief. Laozi in the ''Tao Te Ching'' explains that the ''Tao'' is not a name for a thing, but the underlying natural order of the Universe whose ultimate essence is difficult to circumscribe because it is non-conceptual yet evident in one's being of aliveness. The Tao is "eternally nameless" (''Tao Te Ching''-32. Laozi) and to be distinguished from the countless named things that are considered t ...

I Example Povray Scene Rendering2
I, or i, is the ninth letter and the third vowel letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''i'' (pronounced ), plural '' ies''. History In the Phoenician alphabet, the letter may have originated in a hieroglyph for an arm that represented a voiced pharyngeal fricative () in Egyptian, but was reassigned to (as in English "yes") by Semites, because their word for "arm" began with that sound. This letter could also be used to represent , the close front unrounded vowel, mainly in foreign words. The Greeks adopted a form of this Phoenician ''yodh'' as their letter ''iota'' () to represent , the same as in the Old Italic alphabet. In Latin (as in Modern Greek), it was also used to represent and this use persists in the languages that descended from Latin. The modern letter ' j' originated as a variation of 'i', and both were used interchangeably for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turing-complete
In computability theory, a system of data-manipulation rules (such as a computer's instruction set, a programming language, or a cellular automaton) is said to be Turing-complete or computationally universal if it can be used to simulate any Turing machine (devised by English mathematician and computer scientist Alan Turing). This means that this system is able to recognize or decide other data-manipulation rule sets. Turing completeness is used as a way to express the power of such a data-manipulation rule set. Virtually all programming languages today are Turing-complete. A related concept is that of Turing equivalence two computers P and Q are called equivalent if P can simulate Q and Q can simulate P. The Church–Turing thesis conjectures that any function whose values can be computed by an algorithm can be computed by a Turing machine, and therefore that if any real-world computer can simulate a Turing machine, it is Turing equivalent to a Turing machine. A universal Turi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POV-Ray
The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers. There are also influences from the earlier Polyray raytracer because of contributions from its author, Alexander Enzmann. POV-Ray is free and open-source software, with the source code available under the AGPL-3.0-or-later license. History Sometime in the 1980s, David Kirk Buck downloaded the source code for a Unix ray tracer to his Amiga. He experimented with it for a while and eventually decided to write his own ray tracer named DKBTrace after his initials. He posted it to the "You Can Call Me Ray" bulletin board system (BBS) in Chicago, thinking others might be interested in it. In 1987, Aaron A. Collins downloaded DKBTrace and began working on an x86 port of it. He and David Buck collaborated to add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XL (programming Language)
Christophe de Dinechin is a French computer scientist, with contributions in video games, programming languages and operating systems. Programming languages Dinechin contributed to C++, notably a high-performance exception handling implementation that became a de facto standard in the industry. de Dinechin was one of the proponents of a portable C++ ABI, initially developed for Itanium, but now widely used across platforms. XL programming language Dinechin is the designer of the XL programming language and associated concept programming methodology. "XL" is named for "eXtensible Language". XL features programmer-reconfigurable syntax and semantics. Compiler plug-ins can be used to add new features to the language. A base set of plug-ins implements a relatively standard imperative language. Programmers can write their own plug-ins to implement application-specific notations, such as symbolic differentiation, which can then be used as readily as built-in language features. ...
