2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models and by techniques specific to them. The word may stand for the branch of computer science that comprises such techniques or for the models themselves.
Gimbal lock is the loss of one degree of freedom in a three-dimensional, three-gimbal mechanism that occurs when the axes of two of the three gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system. They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in 3-dimensional linear algebra.
Google Ads is an online advertising platform developed by Google, where advertisers pay to display brief advertisements, service offerings, product listings, video content, and generate mobile application installs within the Google ad network to web users.
A thin-film-transistor liquid-crystal display is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.
In computing, a tiling window manager is a window manager with an organization of the screen into mutually non-overlapping frames, as opposed to the more popular approach of coordinate-based stacking of overlapping objects (windows) that tries to fully emulate the desktop metaphor.
Page orientation is the way in which a rectangular page is oriented for normal viewing. The two most common types of orientation are portrait and landscape. The term "portrait orientation" comes from visual art terminology and describes the dimensions used to capture a person's face and upper body in a picture; in such images, the height of the display area is greater than the width. The term "landscape orientation" also reflects visual art terminology, where pictures with more width than height are needed to fully capture the horizon within an artist's view.
A multiseat, multi-station or multiterminal configuration is a single computer which supports multiple independent local users at the same time.
dwm is a dynamic, minimalist tiling window manager for the X Window System that has influenced the development of several other X window managers, including xmonad and awesome. It is externally similar to wmii, but internally much simpler. dwm is written purely in C for performance and security in addition to simplicity, and lacks any configuration interface besides editing the source code. One of the project's guidelines is that the source code will never exceed 2000 lines, and options meant to be user-configurable are all contained in a single header file.
VR photography is the interactive viewing of wide-angle panoramic photographs, generally encompassing a 360-degree circle or a spherical view. The results is known as VR photograph, 360-degree photo, photo sphere, or spherical photo, as well as interactive panorama or immersive panorama.
iGoogle was a customizable Ajax-based start page or personal web portal launched by Google in May 2005. It was discontinued on November 1, 2013, because the company believed the need for it had eroded over time. As of October 17, 2007, Google had made the service available in many localized versions in 42 languages, and in over 70 country domain-names. In February 2007, 7.1 million people used iGoogle. In April 2008, 20% of all visits to Google's homepage used iGoogle. On July 3, 2012 Google announced iGoogle would be discontinued on November 1, 2013.

In 3D video games, a virtual camera system aims at controlling a camera or a set of cameras to display a view of a 3D virtual world. Camera systems are used in videogames where their purpose is to show the action at the best possible angle; more generally, they are used in 3D virtual worlds when a third person view is required.
MasterImage 3D is a company that develops stereoscopic 3D systems for theaters, and auto-stereoscopic 3D displays for mobile devices.
Sony Ziris is a professional digital signage software application manufactured by Sony Broadcast & Professional Research Laboratories, in Basingstoke, United Kingdom. It was introduced in 2008. The 2010 version claims to manage up to 5,000 displays in a video wall. It works on heterogeneous videowalls comprising panels of different sizes and orientations, or hung at different angles.
Laser-powered phosphor display (LPD) is a large-format display technology similar to the cathode ray tube (CRT). Prysm, Inc., a video wall designer and manufacturer in Silicon Valley, California, invented and patented the LPD technology. The key components of the LPD technology are its TD2 tiles, its image processor and its backing frame that supports LPD tile arrays. The company unveiled the LPD in January 2010.
Concerto is a web-based digital signage application licensed under the Apache License and written using the Ruby on Rails programming framework. It rotates uploaded graphical, textual, and video content through a template that is accessed by computers running a web browser.
