Luxrender
LuxCoreRender is a free and open-source physically based rendering software. It began as ''LuxRender'' in 2008 before changing its name to LuxCoreRender in 2017 as part of a project reboot. The LuxCoreRender software runs on Linux, Mac OS X, and Windows. Overview LuxCoreRender features a 3D renderer; it relies on other programs ( 3D modeling programs) to create the scenes to render, including the models, materials, lights and cameras. This content can then be exported from the application for rendering. For Luxrender, fully functional exporters are available for Blender, Daz Studio; partially functional ones are available for Cinema 4D, Maya, SketchUp and XSI. Luxrender is also fully supported as a production renderer in 3DS Max. For LuxCoreRender, Blender is supported through the BlendLuxCore plugin. After opening the exported file, LuxCoreRender renders the scene. Various tweaks to post processing settings can be set via graphical user interface and the scene control fil ...

Daz Studio
Daz Studio is a free media design software developed by Daz 3D. Daz Studio is a 3D scene creation and rendering application used to produce images as well as video. Renders can be done by leveraging either the 3Delight render engine, or the Iray render engine, both of which ship for free along with Daz Studio, or with a variety of purchasable add-on render engine plugins for Daz Studio from various vendors and companies. Daz Studio also supports the import and export of various file formats for 3D objects and animations to allow for the use of other 3D content within Daz Studio, as well as to get content out of Daz Studio for use in other 3D applications. Version 1.0 was released in Fall 2005. Until version 1.7 its logo was stylized as "DAZ, Studio". On February 1, 2012, Daz 3D announced it would be giving away Daz Studio Pro for free. In 2017, Daz 3D also began offering Hexagon and Daz Studio together for free, thus adding 3D modeling capabilities to the Daz Studio offering. ...

Visible Spectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called ''visible light'' or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual. Under optimal conditions these limits of human perception can extend to 310 nm (ultraviolet) and 1100 nm (near infrared). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well. The spectrum does not contain all the colors that the human visual system can distinguish. '' Unsaturated colors'' such as pink, or purple variations like magenta, for example, are a ...

Unbiased Rendering
__NOTOC__ Within the field of computer graphics, unbiased rendering refers to any rendering (computer graphics), rendering technique that does not introduce systematic error, or bias of an estimator, bias, into the rendering equation, radiance approximation. The term refers to statistical bias, not the broader meaning of Bias, subjective bias. Because of this, an unbiased rendering technique can produce a reference image to compare against renders that use other techniques. In simple terms, unbiased rendering tries to mimic the real world as closely as possible without taking short cuts. Path tracing and its derivatives can be unbiased, whereas Ray tracing (graphics), ray tracing was originally biased. Mathematical definition Mathematically speaking, the expected value (E) of an ''unbiased'' estimator is the population mean, regardless of the number of observations. The error found in a render produced by an unbiased rendering technique is due to random variance, statistical var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cauchy's Equation
In optics, Cauchy's transmission equation is an empirical relationship between the refractive index and wavelength of light for a particular transparent material. It is named for the mathematician Augustin-Louis Cauchy, who defined it in 1837. The equation The most general form of Cauchy's equation is : n(\lambda) = A + \frac + \frac + \cdots, where ''n'' is the refractive index, λ is the wavelength, ''A'', ''B'', ''C'', etc., are coefficients that can be determined for a material by fitting the equation to measured refractive indices at known wavelengths. The coefficients are usually quoted for λ as the vacuum wavelength in micrometres. Usually, it is sufficient to use a two-term form of the equation: : n(\lambda) = A + \frac, where the coefficients ''A'' and ''B'' are determined specifically for this form of the equation. A table of coefficients for common optical materials is shown below: The theory of light-matter interaction on which Cauchy based this equati ...

Thin-film Interference
Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light. When the thickness of the film is an odd multiple of one quarter-wavelength of the light on it, the reflected waves from both surfaces interfere to cancel each other. Since the wave cannot be reflected, it is completely transmitted instead. When the thickness is a multiple of a half-wavelength of the light, the two reflected waves reinforce each other, increasing the reflection and reducing the transmission. Thus when white light, which consists of a range of wavelengths, is incident on the film, certain wavelengths (colors) are intensified while others are attenuated. Thin-film interference explains the multiple colors seen in light reflected from soap bubbles and oil films on water. It is also the mechanism behind the action of antireflection coatings used on glasses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CUDA
CUDA (or Compute Unified Device Architecture) is a parallel computing platform and application programming interface (API) that allows software to use certain types of graphics processing units (GPUs) for general purpose processing, an approach called general-purpose computing on GPUs ( GPGPU). CUDA is a software layer that gives direct access to the GPU's virtual instruction set and parallel computational elements, for the execution of compute kernels. CUDA is designed to work with programming languages such as C, C++, and Fortran. This accessibility makes it easier for specialists in parallel programming to use GPU resources, in contrast to prior APIs like Direct3D and OpenGL, which required advanced skills in graphics programming. CUDA-powered GPUs also support programming frameworks such as OpenMP, OpenACC and OpenCL; and HIP by compiling such code to CUDA. CUDA was created by Nvidia. When it was first introduced, the name was an acronym for Compute Unified Device ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BSD Licenses
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses. BSD is both a license and a class of license (generally referred to as BSD-like). The modified BSD license (in wide use today) is very similar to the license originally used for the BSD version of Unix. The BSD license is a simple license that merely requires that all code retain the BSD license notice if redistributed in source code format, or reproduce the notice if redistributed in binary format. The BSD license (unlike some other licenses e.g. GPL) does not require that source code be distributed at all. Terms In additi ...

Softimage XSI
Autodesk Softimage, or simply Softimage () was a 3D computer graphics application, for producing 3D computer graphics, 3D modeling, and computer animation. Now owned by Autodesk and formerly titled Softimage, XSI, the software has been predominantly used in the film, video game, and advertising industries for creating computer generated characters, objects, and environments. Released in 2000 as the successor to Softimage3D, Softimage, XSI was developed by its eponymous company, then a subsidiary of Avid Technology. On October 23, 2008, Autodesk acquired the Softimage brand and 3D animation assets from Avid for approximately $35 million, thereby ending Softimage Co. as a distinct entity. In February 2009, Softimage, XSI was rebranded Autodesk Softimage. A free version of the software, called ''Softimage Mod Tool'', was developed for the game modding community to create games using the Microsoft XNA toolset for PC and Xbox 360, or to create mods for games using Valve's Source e ...
