: 9 In Stage3D shaders are expressed in a low-level language called Adobe Graphics Assembly Language (AGAL). It was intended to be an equivalent of OpenGL or Direct3D. Initially codenamed Molehill, the official name given to this API was ultimately Stage3D. Originally limited to presenting vector-based objects and images in a simple sequential manner, the format in its later versions allows audio (since Flash 3) and video (since Flash 6).Īdobe introduced a new, low-level 3D API in version 11 of the Flash Player. The binary stream format SWF uses is fairly similar to QuickTime atoms, with a tag, length and payload – an organization that makes it very easy for (older) players to skip contents they don't support. SWF also uses display lists and allows naming and reusing previously defined components. The graphical elements in SWF are thus fairly similar to SVG and MPEG-4 BIFS. Additional primitives like rectangles, ellipses, and even text can be built from these. The main graphical primitive in SWF is the path, which is a chain of segments of primitive types, ranging from lines to splines or bezier curves. On July 1, 2008, Adobe released code to Google and Yahoo, which allowed their search engines to crawl and index SWF files. However, Rob Savoye, a member of the Gnash development team, has pointed to some parts of the Flash format which remain closed. On May 1, 2008, Adobe dropped its licensing restrictions on the SWF format specifications, as part of the Open Screen Project. As Flash became more popular than Shockwave itself, this branding decision became more of a liability, so the format started to be referred to as simply SWF. The original naming of SWF came out of Macromedia's desire to capitalize on the well-known Macromedia Shockwave brand Macromedia Director produced Shockwave files for the end user, so the files created by their newer Flash product tried to capitalize on the already established brand. In December 1996 Macromedia acquired FutureWave and FutureSplash Animator became Macromedia Flash 1.0. FutureWave released FutureSplash Animator in May 1996. The idea involved a format which player software could run on any system and which would work with slower network connections. The small company FutureWave Software originally defined the file format with one primary objective: to create small files for displaying entertaining animations. There is no official resolution to the initialism "SWF" by Adobe. This usage was changed to the backronym Small Web Format to eliminate confusion with a different technology, Shockwave, from which SWF derived. The term "SWF" has originated as an abbreviation for ShockWave Flash. Various other third-party programs can also produce files in this format, such as Multimedia Fusion 2, Captivate and SWiSH Max. Other than using Adobe products, one can build SWFs with open-source Motion-Twin ActionScript 2 Compiler (MTASC), the open-source Ming library and the free-software suite SWFTools. Although Adobe Illustrator can generate SWF format files through its "export" function, it cannot open or edit them. 2016), and After Effects, as well as through MXMLC, a command-line application compiler which forms part of the freely-available Flex SDK. Programmers can generate SWF files from within several Adobe products, including Flash, Flash Builder (an IDE), Adobe Animate (the replacement for Adobe Flash as of Feb. They may also occur in programs, commonly browser games, using ActionScript. Originating with FutureWave Software, then transferred to Macromedia, and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function. SWF ( / ˈ s w ɪ f/ SWIF / ˈ s w ʊ f/ SWOOF) is an Adobe Flash file format used for multimedia, vector graphics and ActionScript.
