LambdaMOO has its roots in the 1978 – 1980 work by Roy Trubshaw and Richard Bartle to create and expand the concept of Multi-User Dungeon ( MUD ) – virtual communities.

The modelling earned him 15 shillings an hour, Student artist Richard Demarco who painted several notable early pictures of Connery described the young Connery as " very straight, slightly shy, too, too beautiful for words, a virtual Adonis.

The virtual Richard Burton was also improved ; the whole face was animated ( an actor was found with a similar facial structure, all of Burton's narrative parts were mimed, and his face was super-imposed onto the face of the actor ).

Richard Bartle argued that this aspect negates the whole idea of ownership in virtual worlds, and thus in the absence of real ownership no real trade may occur.

* Dr. Richard A. Bartle, Pitfalls of Virtual Property – A philosophical case against the concept of " virtual property " ownership.

In 1989, actor Jack Douglas and Richard Hope-Hawkins, organised a benefit concert for Thomas, after discovering he was living in virtual obscurity and ill health.

Lerner and Loewe, impressed by Goulet's talent, signed the virtual newcomer to play the part, opposite Richard Burton ( King Arthur ) and Julie Andrews ( Queen Guenevere ).

In his book Designing Virtual Worlds, Richard Bartle ( co-creator of the original MUD ) cited DikuMUD as one of the five " major codebases used for ( textual ) virtual worlds ".

In a given country, the Virgin Mobile wireless entity is typically a partnership between Sir Richard Branson's Virgin Group and an existing mobile network operator or mobile virtual network operator.

MUDs are a class of multi-user real-time virtual worlds, usually but not exclusively text-based, with a history extending back to the creation of MUD1 by Richard Bartle in 1978.

GmailFS is a virtual file system originally developed by Richard Jones that uses a Gmail e-mail account for storage.

It was created and hosted by Richard Hart and showcased the latest in cutting-edge technology and its applications from electric vehicles to virtual reality.

Fifty days later they discover that the Xeelees ' project has been destroyed but a recently awakened virtual of Michael Poole shows Spinner-of-Rope, a primitive, how to pilot around the fragmented cosmic strings and travel into the past using a closed time-like path ; this method of time travel was first suggested by J. Richard Gott.

An upright image formed by reflection in a mirror is always virtual, while an inverted image is real and can be projected onto a screen.

They often consist of a replication of a ships ' bridge, with operating console ( s ), and a number of screens on which the virtual surroundings are projected.

* 1994: Julie Martin creates first ' Augmented Reality Theater production ', Dancing In Cyberspace, funded by the Australia Council for the Arts, features dancers and acrobats manipulating body – sized virtual object in real time, projected into the same physical space and performance plane.

First generation virtual product placement has tended to be based upon sports arenas where the geometrical relationships of camera and the surface of the flat area onto which the billboard is projected, can be easily calculated.

It was a small silver tube that projected a hologram and lasers which would detect where the hands were, eliminating the need even for virtual reality gloves.

* It is virtual, meaning that the image appears to be behind the mirror, and cannot be projected onto a screen.

An upright image formed by reflection in a mirror is always virtual, while an inverted image is real and can be projected onto a screen.

As digital cinema catches on, the physical reel is being replaced by a virtual format called Digital Cinema Package, which can be distributed using any storage media ( such as hard drives ) or data transfer medium ( such as the Internet or satellite links ) and projected using a digital projector instead of a conventional movie projector.

The anchor sits behind a desk in front of a green screen, onto which a virtual reality studio is digitally projected.

The real image is either viewed directly or, as in the case with most head-mounted displays, projected through an optical system and the resulting virtual image is viewed.

I was an instrument in a virtual world that constantly renewed its own meaningless image in a living world that was itself perceived outside of nature.

Some of these instruments produce a virtual image when applied to the human eye ; others produce a real image which can be captured on photographic film or an optical sensor, or can be viewed on a screen.

* In a plane mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel ; the images formed by a plane mirror are virtual images, of the same size as the original object ( see mirror image ).

With concave lenses, incoming parallel rays diverge after going through the lens, in such a way that they seem to have originated at an upright virtual image one focal length from the lens, on the same side of the lens that the parallel rays are approaching on.

Rays from an object at finite distance are associated with a virtual image that is closer to the lens than the focal length, and on the same side of the lens as the object.

The closer the object is to the lens, the closer the virtual image is to the lens.

Note that E ( at 2f ) has an equal-size, real and inverted image ; I ( at f ) has its image at infinity ; and K ( at f / 2 ) has a double-size, virtual and upright image.

** 3D rendering, generating image or motion picture from virtual 3D models

In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects.

Later ( in 1983 ) a general availability implementation, known as Smalltalk-80 Version 2, was released as an image ( platform-independent file with object definitions ) and a virtual machine specification.

In practice, it is currently very difficult to create a high-fidelity virtual reality experience, due largely to technical limitations on processing power, image resolution, and communication bandwidth ; however, the technology's proponents hope that such limitations will be overcome as processor, imaging, and data communication technologies become more powerful and cost-effective over time.

In a layer-based model, the target image is produced by " painting " or " pasting " each layer, in order of decreasing depth, on the virtual canvas.

Squeak 4. 0 may be downloaded at no cost, including source code, as a prebuilt virtual machine image licensed under the MIT License, with the exception of some of the original Apple code, which is governed by the Apache License.

In a monopole antenna, the radiation pattern of the monopole plus the virtual " image antenna " make it appear as a two element center-fed dipole antenna.

Because of the reflection, these second waves appear to come from a second antenna behind the plane, just as a visible object in front of a flat mirror forms a virtual image that seems to lie behind the mirror.

Many instances of such a boot image create a virtual dedicated host.

; Super VGA virtual screens: Allows software to set up virtual display resolutions, larger than the actual displayed resolution, and smoothly scroll or pan around the larger image.

Note that E ( at 2f ) has an equal-size, real and inverted image ; I ( at f ) has its image at infinity ; and K ( at f / 2 ) has a double-size, virtual and upright image.
