The computer technology that allows us to develop three-dimensional virtual environments VEs consists of both hardware and software. The current popular, technical, and scientific interest in VEs is inspired, in large part, by the advent and availability of increasingly powerful and affordable visually oriented, interactive, graphical display systems and techniques. Graphical image generation and display capabilities that were not previously widely available are now found on the desktops of many professionals and are finding their way into the home. The greater affordability and availability of these systems, coupled with more capable, single-person-oriented viewing and control devices e. Limiting VE technology to primarily visual interactions, however, simply defines the technology as a more personal and affordable variant of classical military and commercial graphical simulation technology.
Computer-aided design CAD involves creating computer models defined by geometrical parameters. These models typically appear on a computer monitor as a three-dimensional representation of a part or a system of parts, which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions. Computer-aided manufacturing CAM uses geometrical design data to control automated machinery. These systems differ from older forms of numerical control NC in that geometrical data are encoded mechanically. Since both CAD and CAM use computer-based methods for encoding geometrical data, it is possible for the processes of design and manufacture to be highly integrated. CAD had its origins in three separate sources, which also serve to highlight the basic operations that CAD systems provide.
You will learn how commands are entered using the menus, keyboard, toolbars, etc. The second smallest unit of memory is a byte, which contains 8 bits. One megabyte contains one million bytes. Digitizer An electronic data input device. Dots per inch dpi A specification of printers and plotters that determines how accurately they can print. Dot-pitch The distance between the picture elements pixels on the screen.
The computer-aided design/computer-aided manufacturing (CAD/CAM) systems were introduced into dentistry in s. This technology has evolved rapidly.
Evolution of the Software and Hardware in CAD/CAM Systems used in Dentistry
When most people envision a construction worker, they see a person at a construction site wearing a hard hat and a safety vest. Perhaps this person is putting up drywall, hammering nails, laying flooring, or even having lunch high above the ground, evoking the iconic Lunch Atop a Skyscraper photograph. Although all these constitute part of the job, construction is in many ways a tech job. With a name change to AD along with more machining and surfacing capabilities, the program became a hit.

Computer-aided design CAD is the use of computers or workstations to aid in the creation, modification, analysis, or optimization of a design. The term CADD for c omputer aided design and drafting is also used. Its use in designing electronic systems is known as electronic design automation EDA.
