In computer graphics, alpha compositing is the process of combining an image with a background to create the appearance of partial or full transparency.

Alpha blending is a convex combination of two colors allowing for transparency effects in computer graphics.

Because the original designer had left the company another employee completely redesigned most of the system, ( adding a display snow remover circuit, true 80 / 64 column text mode support, ( with different size letters for TRS-80 and CP / M mode, so that in TRS-80 mode the full screen was also used, not just a 64x16 portion of the 80x25 screen ) with an improved font set ( adding " gray scale " version of the TRS-80 mozaik graphics and many special PETSCII like characters ), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements ), also an enclosure was developed for the main computer system, ( in the form of a 19-inch rack for the Eurocards ) and for two floppy disk drives and the power supply.

The Accelerated Graphics Port ( often shortened to AGP ) is a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.

However, some home computer manufacturers extended the ASCII character set to take advantage of the advanced color and graphics capabilities of their systems.

A Bézier curve is a parametric curve frequently used in computer graphics and related fields.

Bézier curves are widely used in computer graphics to model smooth curves.

Some, such as computational complexity theory, which studies fundamental properties of computational problems, are highly abstract, while others, such as computer graphics, emphasize real-world applications.

Some fields, such as computational complexity theory ( which explores the fundamental properties of computational problems ), are highly abstract, whilst fields such as computer graphics emphasise real-world applications.

Rendering is one of the major sub-topics of 3D computer graphics, and in practice always connected to the others.

With the increasing sophistication of computer graphics since the 1970s, it has become a more distinct subject.

Computer animation is the process used for generating animated images by using computer graphics.

Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings.

Developments in CGI technologies are reported each year at SIGGRAPH, an annual conference on computer graphics and interactive techniques, attended each year by tens of thousands of computer professionals.

In this Graphics Interchange Format |. gif of a 2D Adobe Flash | Flash animation, each ' stick ' of the stick figure | figure is Keyframe # Animation by means of computer graphics | keyframed over time to create motion.

Although modern cathode ray tubes used in televisions and computer displays have epoxy-bonded face-plates or other measures to prevent shattering of the envelope, CRTs must be handled carefully to avoid personal injury.

Using cathode ray tubes, Fred Williams would invent the Williams tube, which would be the first random access computer memory.

These are used in cathode ray tubes, found in televisions and computer monitors, and in electron microscopes.

Most radios and television sets prior to the 1970s used filament-heated-cathode electron tubes for signal selection and processing ; to this day, a hot cathode forms the source of the electron beam ( s ) in cathode ray tubes in many television sets and computer monitors.

The first computer monitors used cathode ray tubes ( CRT ).

Electrons are at the heart of cathode ray tubes, which have been used extensively as display devices in laboratory instruments, computer monitors and television sets.

One common application of the RGB color model is the display of colors on a cathode ray tube ( CRT ), liquid crystal display ( LCD ), plasma display, or organic light emitting diode ( OLED ) display such as a television, a computer ’ s monitor, or a large scale screen.

Optical ray tracing describes a method for producing visual images constructed in 3D computer graphics environments, with more photorealism than either ray casting or scanline rendering techniques.

If the surface at this point faces a light, a ray ( to the computer, a line segment ) is traced between this intersection point and the light.

On March 16, 2007, the University of Saarland revealed an implementation of a high-performance ray tracing engine that allowed computer games to be rendered via ray tracing without intensive resource usage.

Electronic amplifiers of various types are used to amplify the signals, which are displayed as variations in brightness on a computer monitor ( or, for vintage models, on a cathode ray tube ).

In older microscopes image may be captured by photography from a high-resolution cathode ray tube, but in modern machines image is saved to a computer data storage.

Cathodoluminescence is most commonly experienced in everyday life as the light emission from the inner surface of the cathode ray tube in television sets and computer CRT monitors.

It was developed on the EDSAC computer, which uses a cathode ray tube as a visual display to display memory contents.

The Williams tube, better called the Williams-Kilburn tube ( after inventors Freddie Williams and Tom Kilburn ), developed in 1946 and 1947, was a cathode ray tube used as a computer memory to electronically store binary data.

* Common televisions and computer monitors: TV and computer screens containing a cathode ray tube employ an electromagnet to guide electrons to the screen.

Please note that at the birth of DVI, most computer monitors were of the Cathode ray tube type ones that required the analog video synchronization signals.

Moiré patterns are often an undesired artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane ( the latter being a special case of aliasing, due to undersampling a fine regular pattern ).

Other applications include performing geometrical operations with shapes ( constructive solid geometry ) in CAD, collision detection in robotics and 3-D video games, ray tracing and other computer applications that involve handling of complex spatial scenes.

First the screen is brightened and the response time is measured as in cathode ray timing, but the computer measures only which scanline was hit and not which horizontal pixel was hit.

Before the advent of LCD screens, most computer screens were based on cathode ray tubes ( CRTs ).

GDB offers extensive facilities for tracing and altering the execution of computer programs.

Several perspectives or branches of such academic dictionary research have been distinguished: ' dictionary criticism ' ( or evaluating the quality of one or more dictionaries, e. g. by means of reviews ( see Nielsen 2009 )), ' dictionary history ' ( or tracing the traditions of a type of dictionary or of lexicography in a particular country or language ), ' dictionary typology ' ( or classifying the various genres of reference works, such as dictionary versus encyclopedia, monolingual versus bilingual dictionary, general versus technical or pedagogical dictionary ), ' dictionary structure ' ( or formatting the various ways in which the information is presented in a dictionary ), ' dictionary use ' ( or observing the reference acts and skills of dictionary users ), and ' dictionary IT ' ( or applying computer aids to the process of dictionary compilation ).

Professional pucks often have a reticle or loupe which allows the user to see the exact point on the tablet's surface targeted by the puck, for detailed tracing and computer aided design ( CAD ) work.

* Ray tracing ( computer graphics )

On the other hand, photocopier-generated overlays where no tracing is used is considered to be the best method in matching the correct bite mark to the correct set of models without the use of computer imaging.

Although " ray casting " and " ray tracing " were often used interchangeably in early computer graphics literature,

Attempting to simulate this real-world process of tracing light rays using a computer can be considered extremely wasteful, as only a minuscule fraction of the rays in a scene would actually reach the eye.

As polygonal meshes are extensively used in computer graphics, algorithms also exist for Ray tracing, collision detection, and rigid-body dynamics of polygon meshes.

It includes an interactive geometry editor, ray tracing support for graphics rendering and geometric analysis, computer network distributed framebuffer support, scripting, image-processing and signal-processing tools.

* Ray tracing, techniques in computer graphics or physics

* Minimal ray tracing: At the time that Reyes was proposed, computer systems were significantly less capable in terms of processing power and storage.

One interesting aspect of real-time computer graphics is the way in which it differs from traditional off-line rendering systems ( and hence, these are the non-real-time graphics systems ); non-real-time graphics typically rely on ray-tracing where the expensive operation of tracing rays from the camera to the world is allowed and can take as much as hours or even days for a single frame.

Modern computer graphics programs that use ray tracing often trace lines of sight from " eyes " to objects and thence to light sources to determine the colour and luminance of pixels in a simulated scene.

It is essentially an application of the Monte Carlo method to 3D computer graphics, and for this reason is also called stochastic ray tracing.
