Unreferenced date December 2009 In deliberative procedure , compositing is the process of combining several motion democracy motion s into one composite motion . The process of compositing motions may be desirable for two reasons. First, it can save the time of an Deliberative assembly assembly by avoiding presenting two or more similar motions. Second, it can increase the amount of support for the main provisions of two or more motions by producing a composite motion for which the supporters of each motion are likely to vote . The major disadvantages of compositing are also twofold. The motions composited may, in some respects, be dissimilar some of their supporters will not wish to vote for some provisions of the combined motion. Some provisions may have to be omitted from the composite motions to reduce its length or because the supporters of the original motions will not agree to them. The procedure of submitting motions to some meeting conferences includes one or more rounds of compulsory compositing in other cases, the compositing may be informal.

Multiple issues wikify August 2010 orphan August 2010 Deep image compositing is a recently emerged way of compositing and rendering digital images. In addition to the usual color and opacity channels a notion of depth is created. This allows multiple samples in the depth of the image to make up the final resulting color. This technique is producing high quality results and removes artefacts around edges that could not be dealt with otherwise. Deep data Deep data is an image that holds additional information about each pixel along the z axis like multi layered images where each layer has a depth associated with. But unlike Voxel s only at some arbitary specified points in depth. The data can be evaluated through different types of interpolation . Function based integrated The data is stored as a function of depth. This results in a function curve that can be used to look up the data at any arbitrary depth. Manipulating the data is harder. Sample based deintegrated Each sample is considered as an independent piece and can so be manipulated easily. To make sure the data is representing the right detail an additional expand value needs to be introduced. Generating deep data 3D renderer s produce the necessary data as a part of the rendering pipeline. Samples are gathered in depth and then combined. The deep data can be written out before this happens and is so nothing new to the process. Generating deep data from camera data needs a proper depth map. This is used in a couple of cases but still not accurate enough for detailed representation. For basic holdout task this can be sufficient though. Compositing deep data images Deep images can be Compositing composited like regular images. The depth component makes it easier to determine the layering order. This must traditionally be input by a user. Deep images have that information for themselves and need no user input. Edge artifacts are reduced as transparent pixels have more data to work with.

Unreferenced stub auto yes date December 2009 Avid Media Illusion was a digital nonlinear compositing software by Avid Technology targeted at the film and television markets. It ran on Silicon Graphics workstation s. The main features were paint, compositing, image manipulation and special effects. History Illusion was originally developed by Parallax Software under the name Advance . Avid later bought Parallax, and renamed Advance to Media Illusion . The software was discontinued on December 6, 2001, officially due to lack of resources to support it any further. Media Illusion was targeted at the high end SGI post production market, which was at the time dominated by Discreet Flame Discreet Flame . In 2001, Softimage , a division of Avid, introduced a new image compositing module in its 3D animation product Softimage XSI 2.0 which is based on Media Illusion 6.0. The product offers and augments many of the essential image compositing features of Media Illusion on Windows and Linux, but does not offer the video digitizing and playback support, and the OMFI media integration and editing which helped Media Illusion make its place in high end broadcast. The compositing module integrated in XSI 6.0 2000 USD targets RGBA file based desktop compositing for the 3D artist. Features Media Illusion featured distributed rendering using multiple CPUs. Several specialized plug ins were available from Sapphire, The Foundry, Primatte and Ultimatte, among others.

Alpha to coverage is a Multisample anti aliasing multisampling computer graphics technique useful for situations where dense foliage or grass must be rendered in a video game . This technique uses the Alpha compositing alpha channel of Texture mapping textures as a Mask computing Image masks coverage mask for anti aliasing . Alpha to coverage multisampling is based on regular multisampling, except that the Alpha compositing alpha coverage mask is Bitwise AND AND ANDed with the multisample mask. Alpha to coverage converts the Alpha compositing alpha component output from the pixel shader to a coverage mask. When the Multisample anti aliasing multisampling is applied each output fragment gets a transparency of 0 or 1 depending on alpha coverage and the Multisample anti aliasing multisampling result.

unreferenced date June 2007 Industrial Light and Magic s proprietary Sabre compositing technology is actually based on Discreet Logic s Inferno and Flame. Several key innovation s separate it from the Commercial off the shelf off the shelf versions. Most important is the tools that accurately deal with logarithm ic color conversions into and out of the system. Several node s were also written to accurately process images in logarithmic color space . Company folklore states that the name Sabre was quickly created because Discreet Logic didn t want to offer a discount to Industrial Light & Magic ILM in exchange for use of their name in marketing materials. Of much greater significance to the history of digital compositing would be Industrial Light & Magic ILM s Proprietary software proprietary CompTime application. It was written entirely from scratch by ILM programmers. It relies heavily on Python programming language python programming and is very customizable by artists with only a cursory knowledge of Scripting language scripting and programming. Still in use today, it has handled the majority of visual effects shots created by ILM.
