ADM Laser Tracker are the newest portable laser station from API features API`s advanced TurboADM system which makes precision measurements, inspections and alignments easier than ever before. Easier to use than a total station and more affordable than a laser tracker, the Omnitrac™ provides the best possible value and performance for your measurement task.
To create the OmniTrac™, API started with the rugged and proven mechanical design of our Tracker3™ and worked to create a lower cost, ADM only system. The Omnitrac™ has all of the advantages of the Tracker3™ platform: industry leading size and portability, advanced design, one-man operation, simple setup, instant power start, Turbo ADM, and a large measurement envelope.
All of this 3D stuff began back in the 386 era when Wolfenstien 3D came out. It was an outrageously popular game for the time, showing people that their lowly PCs can do more than they thought. People were absolutely amazed that PCs could display 3D imagery at interactive frame rates. Even on high powered graphics workstations, you couldn't do that. Well, ID proved everyone wrong.
The idea behind Wolf3d is that all of the walls are spaced evenly on an 8x8 foot grid. In other words, each of the walls had to be aligned to a multiple of 90 degrees, and had to be the same height. These restrictions made it possible to make many assumptions about the engine and make rendering very fast. The floor and ceiling of the environment was not texture mapped, but it was added to the engine in games after it, such as Blake Stone.
Doom took a radically different approach to rendering the 3 dimensional data. It is a true polygonal engine, but it has limitations of it's own. These limitations include the inability to tilt the view, and the inability to have walls that are not vertical. Also, you cannot have maps that have more than one level in the same place. Although these limitations are certainly much less than Wolf's, they aren't bad. Doom was a break through in technology.
