Digital Compositing
Digital compositing is the process of digitally assembling multiple images to make a final image, typically for print, motion pictures or screen display. It is the digital analogue of optical film compositing. It's part of VFX processing. Mathematics The basic operation used in digital compositing is known as alpha blending, where an opacity value, 'α', is used to control the proportions of two input pixel values that end up a single output pixel. As a simple example, suppose two images of the same size are available and they are to be composited. The input images are referred to as the foreground image and the background image. Each image consists of the same number of pixels. Compositing is performed by mathematically combining information from the corresponding pixels from the two input images and recording the result in a third image, which is called the composited image. Consider three pixels; * a foreground pixel, f * a background pixel, b * a composited adetpixel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parallelism (computing)
Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Parallelism has long been employed in high-performance computing, but has gained broader interest due to the physical constraints preventing frequency scaling.S.V. Adve ''et al.'' (November 2008)"Parallel Computing Research at Illinois: The UPCRC Agenda" (PDF). Parallel@Illinois, University of Illinois at Urbana-Champaign. "The main techniques for these performance benefits—increased clock frequency and smarter but increasingly complex architectures—are now hitting the so-called power wall. The computer industry has accepted that future performance increases must largely come from increasing the number of processors (or cores) on a die, rather than mak ...

Rendering (computer Graphics)
Rendering is the process of generating a physically-based rendering, photorealistic or Non-photorealistic rendering, non-photorealistic image from input data such as 3D models. The word "rendering" (in one of its senses) originally meant the task performed by an artist when depicting a real or imaginary thing (the finished artwork is also called a "architectural rendering, rendering"). Today, to "render" commonly means to generate an image or video from a precise description (often created by an artist) using a computer program. A application software, software application or component-based software engineering, component that performs rendering is called a rendering software engine, engine, render engine, : Rendering systems, rendering system, graphics engine, or simply a renderer. A distinction is made between Real-time computer graphics, real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or an ...

Blackmagic Fusion
Blackmagic Fusion (formerly eyeon Fusion and briefly Maya Fusion, a version produced for Alias-Wavefront) is post-production image compositing developed by Blackmagic Design and originally authored by eyeon Software. It is typically used to create visual effects and digital compositing for movies, TV-series and commercials and employs a node-based interface in which complex processes are built up by connecting a flowchart or schematic of many nodes, each of which represents a simpler process, such as a blur or color correction. This type of compositing interface allows great flexibility, including the ability to modify the parameters of an earlier image processing step "in context" (while viewing the final composite). Upon its acquisition by Blackmagic Design, Fusion was released in two versions: the freeware Fusion, and the commercially sold Fusion Studio. Fusion is available for Linux, Microsoft Windows, and with the release of Fusion 8, macOS. History Fusion was original ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blender (software)
Blender is a Free and open-source software, free and open-source 3D computer graphics software tool set that runs on Microsoft Windows, Windows, macOS, BSD, Haiku (operating system), Haiku, IRIX and Linux. It is used for creating animated films, visual effects, art, 3D printing, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality.

Apple Shake
Shake is a discontinued image compositing package used in the post-production industry developed by Nothing Real for Windows and later acquired by Apple Inc. Shake was widely used in visual effects and digital compositing for film, video and commercials. Shake exposed its node graph architecture graphically. It enabled complex image processing sequences to be designed through the connection of effects "nodes" in a graphical workflow interface. This type of compositing interface allowed great flexibility, including the ability to modify the parameters of an earlier image processing step "in context" (while viewing the final Composite image, composite). Many other compositing packages, such as Blender (software), Blender, Blackmagic Fusion, Nuke (software), Nuke and Cineon, also used a similar node-based approach. Shake 4 was available for Mac OS X and Linux. Support for Microsoft Windows and IRIX was discontinued in previous versions. On July 30, 2009, Apple discontinued Shake. N ...

Natron (software)
Natron is a free and open-source node-based compositing application. It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived. Natron supports plugins following the OpenFX 1.4 API. Most open-source and commercial OpenFX plug-ins are supported. Origin of the name Natron is named after Lake Natron in Tanzania which, according to Natron lead programmer Alexandre Gauthier, provides "natural visual effects" by preserving its dead animals. History Natron was started by Alexandre Gauthier-Foichat in June 2012 as a personal project. The project was the winner of the 2013 ''Boost Your Code'' contest by Inria. The prize was a 12-month employment contract to develop Natron as a free and open-source software within the institute.

Keyframing
In animation and filmmaking, a key frame (or keyframe) is a drawing or shot that defines the starting and ending points of a smooth transition. These are called ''frames'' because their position in time is measured in frames on a strip of film or on a digital video editing timeline. A sequence of key frames defines which movement the viewer will see, whereas the position of the key frames on the film, video, or animation defines the timing of the movement. Because only two or three key frames over the span of a second do not create the illusion of movement, the remaining frames are filled with " inbetweens". Use of key frames as a means to change parameters In software packages that support animation, especially 3D graphics, there are many parameters that can be changed for any one object. One example of such an object is a light. In 3D graphics, lights function similarly to real-world lights. They cause illumination, cast shadows, and create specular highlights. Lights have man ...

Directed Acyclic Graph
In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called ''arcs''), with each edge directed from one vertex to another, such that following those directions will never form a closed loop. A directed graph is a DAG if and only if it can be topologically ordered, by arranging the vertices as a linear ordering that is consistent with all edge directions. DAGs have numerous scientific and computational applications, ranging from biology (evolution, family trees, epidemiology) to information science (citation networks) to computation (scheduling). Directed acyclic graphs are also called acyclic directed graphs or acyclic digraphs. Definitions A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph, each edg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colour Correction
Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature, as well as along a green–magenta axis orthogonal to the color temperature axis. Without color-correction gels, a scene may have a mix of various colors. Applying color-correction gels in front of light sources can alter the color of the various light sources to match. Mixed lighting can produce an undesirable aesthetic when displayed on a television or in a theatre. Conversely, gels may also be used to make a scene ''appear'' more natural by simulating the mix of color temperatures that occur naturally. This application is useful, especially where ''motivated lighting'' (lending the impression that it is diegetic) is the goal. Color gels may also be used to tint lights for artistic effect. Correlated color tem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photograph Manipulation
Photograph manipulation involves the transformation or alteration of a photograph. Some photograph manipulations are considered to be skillful artwork, while others are considered to be unethical practices, especially when used to deceive. Motives for manipulating photographs include political propaganda, altering the appearance of a subject (both for better and for worse), entertainment and humor. Depending on the application and intent, some photograph manipulations are considered an art form because they involve creation of unique images and in some instances, signature expressions of art by photographic artists. For example, Ansel Adams used darkroom exposure techniques to darken and lighten photographs. Other techniques include retouching using ink or paint, airbrushing, double exposure, piecing photos or negatives together in the darkroom, and scratching instant films. Software for digital image manipulation ranges from casual to professional skillsets. One of these, Ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
