PowerPoint Animation
PowerPoint animation is a form of animation which uses Microsoft PowerPoint and similar programs to create a game or movie. The artwork is generally created using PowerPoint's AutoShape features, and then animated slide-by-slide or by using Custom Animation. These animations can then be shared by transferring the PowerPoint file they were created in, and can be viewed with PowerPoint or Microsoft's free PowerPoint Viewer and are often exported to video formats such as mp4. Custom Animation A set of effects which can be applied to objects in PowerPoint so that they will animate in the Slide Show. They can be added under the Custom Animation function or through the use of Visual Basic for Applications (VBA). PowerPoint 2000 and earlier versions introduced basic effects such as Appear, Dissolve, Fly In and so forth. In PowerPoint 2002/XP and later versions, the Custom Animation feature was improved, adding new animation effects grouped into four categories: Entrance, Emphasis, Exit, ...

Key Frame
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 ...

Calligra Stage
Calligra Stage (formerly ''KPresenter'') is a free presentation program that is part of the Calligra Suite, an integrated office suite developed by KDE. Calligra Stage's native export format is OpenDocument. Stage is able to load presentation documents from Microsoft PowerPoint, LibreOffice Impress and OpenOffice Impress. In 2014, development of Calligra Gemini with official support for Windows was announced. History As KPresenter Reginald Stadlbauer began development of KPresenter in 1997. The first official release of the KOffice suite was on October 23, 2000 when it was released as part of K Desktop Environment 2.0. Versions 1.1 followed in 2001, 1.2 in 2002, 1.3 in 2004, 1.4 in 2005, and 1.5 and 1.6 both in 2006. KOffice underwent a major transition as part of the release of KDE Software Compilation 4 (''SC4''). Coinciding with the work on SC4, the KOffice team prepared a major new release – KOffice 2.0 – which used the new KDE Platform 4 libraries. Although versio ...

LibreOffice Impress
LibreOffice () is a free and open-source productivity software, office productivity software suite, a project of The Document Foundation (TDF). It was fork (software development), forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice. The LibreOffice suite consists of programs for word processing, creating and editing of spreadsheets, slideshows, diagrams and drawings, working with databases, and composing mathematical formulae. It is available in 115 languages. TDF doesn't provide support for LibreOffice, but enterprised-focused editions are available from companies in the ecosystem. LibreOffice uses the OpenDocument standard as its native file format, but supports formats of most other major office suites, including Microsoft Office, through a variety of import and export filters. LibreOffice is available for a variety of computing platforms, with official support for Microsoft Windows, macOS and Linux and community builds for many other platfo ...

ZIP (file Format)
ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP format was then quickly supported by many software utilities other than PKZIP. Microsoft has included built-in ZIP support (under the name "compressed folders") in versions of Microsoft Windows since 1998 via the "Windows Plus!" addon for Windows 98. Native support was added as of the year 2000 in Windows ME. Apple has included built-in ZIP support in Mac OS X 10.3 (via BOMArchiveHelper, now Archive Utility) and later. Most free operating systems have built in support for ZIP in similar manners to Windows and Mac OS X. ZIP files ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Portability
A computer program is said to be portable if there is very low effort required to make it run on different platforms. The pre-requirement for portability is the generalized abstraction between the application logic and system interfaces. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. Strategies for portability Software portability may involve: * Transferring installed program files to another computer of basically the same architecture. * Reinstalling a program from distribution files on another computer of basically the same architecture. * Building executable programs for different platforms from source code; this is what is usually understood by "porting". Similar systems When operating systems of the same family are installed on two computers with processors with similar instruction sets it is often possible to transfer the files implementing program files between the ...

SVG Animation
Animation of Scalable Vector Graphics, an open XML-based standard vector graphics format is possible through various means: * Scripting: ECMAScript is a primary means of creating animations and interactive user interfaces within SVG. * Styling: Since 2008, the development of CSS Animations as a feature in WebKit has made possible stylesheet-driven implicit animation of SVG files from within the Document Object Model (DOM). * SMIL: Synchronized Multimedia Integration Language, a recommended means of animating SVG-based hypermedia, supported by the Amaya (2003) Opera (2006), Mozilla Firefox (2011), Google Chrome (2016) and Safari (2017) web browsers, and any browser that aims to pass the Acid3 web standards test of 2008 (i.e. before the test's "simplification" in 2011) as this requires SMIL support for tests 75 and 76. Libraries have also been written as a shim to give current SVG-enabled browsers SMIL support. This method is also known as SVG+Time. Because SVG supports Portab ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Macro Virus (computing)
In computing terminology, a macro virus is a virus that is written in a macro language: a programming language which is embedded inside a software application (e.g., word processors and spreadsheet applications). Some applications, such as Microsoft Office, Excel, PowerPoint allow macro programs to be embedded in documents such that the macros are run automatically when the document is opened, and this provides a distinct mechanism by which malicious computer instructions can spread. This is one reason it can be dangerous to open unexpected attachments in e-mails. Many antivirus programs can detect macro viruses; however, the macro virus' behavior can still be difficult to detect . Fundamentals A macro is a series of commands and actions that helps automating some tasks - usually a quite short and simple program. However they are created, they need to be executed by some system which interprets the stored commands. Some macro systems are self-contained programs, but others ...

Direct3D
Direct3D is a graphics application programming interface (API) for Microsoft Windows. Part of DirectX, Direct3D is used to render three-dimensional graphics in applications where performance is important, such as games. Direct3D uses hardware acceleration if it is available on the graphics card, allowing for hardware acceleration of the entire 3D rendering pipeline or even only partial acceleration. Direct3D exposes the advanced graphics capabilities of 3D graphics hardware, including Z-buffering, W-buffering, stencil buffering, spatial anti-aliasing, alpha blending, color blending, mipmapping, texture blending, clipping, culling, atmospheric effects, perspective-correct texture mapping, programmable HLSL shaders and effects. Integration with other DirectX technologies enables Direct3D to deliver such features as video mapping, hardware 3D rendering in 2D overlay planes, and even sprites, providing the use of 2D and 3D graphics in interactive media ties. Direct3D contains many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tweening
Inbetweening, also known as tweening, is a process in animation that involves creating intermediate frames, called inbetweens, between two keyframes. The intended result is to create the illusion of movement by smoothly transitioning one image into another. Traditional animation Traditional inbetweening involves the use of a light table to draw a set of pencil and paper drawings. The process of inbetweening in traditional animation starts with a primary artist, who draws key frames to define movement. After the testing and approval of a rough animation, the scene is passed down to assistants, who perform clean-up and add necessary inbetweening. In large studios, assistants usually add breakdowns, which define the movement in more detail. The scene is then passed down to another assistant, the inbetweener who completes the animation. In small animation teams, animators will often carry out the full inbetweening process themselves. Dick Huemer developed this system in the 1920s, a ...
