Text and graphics could be mixed, and there were additional tools for drawing axes and markers. The waveform graphics system was used only for a short period of time before it was replaced by the more sophisticated ReGIS system, first introduced on the VT125 in 1981. [1] ReGIS allowed the construction of arbitrary vectors and other shapes.
[26] [27] The Laboratory was an enormous influence on the commercial Environmental Systems Research Institute, Esri, founded in 1969 by Jack Dangermond, a landscape architect graduate of Harvard Graduate School of Design who had worked as a research assistant at the Laboratory during 1968 and 1969. Scott Morehouse, the development lead for the ...
The first Genigraphics systems (100 Series and 100A Series) used an array of buttons, dials, knobs and joysticks, along with a built in keyboard, as the means of user interface. The PDP-11/40 computer was housed in a tall cabinet and used random access magnetic tape drives (DECtape) for storing completed presentations.
A surface may be composed of one or more patches, where each patch has its own U-V coordinate system. These surface patches are analogous to the multiple polynomial arcs used to build a spline. They allow more complex surfaces to be represented by a series of relatively simple equation sets rather than a single set of complex equations.
A scientific visualization of a simulation of a Rayleigh–Taylor instability caused by two mixing fluids. [1] Surface rendering of Arabidopsis thaliana pollen grains with confocal microscope. Scientific visualization (also spelled scientific visualisation) is an interdisciplinary branch of science concerned with the visualization of scientific ...
This was used because it had good color density and contrast - also because it was less costly as surplus for some years. Exposures vary from 1/20 at f1.2 to f2, closeup at about 15 inches from scope screen. Cameras used were a Praktica and a Nikon. For the 4x5 work I used a B&J press with a German war surplus aerial lens, an f2 tessar if 120mmf.1.
Surface-wave inversion is the method by which elastic properties, density, and thickness of layers in the subsurface are obtained through analysis of surface-wave dispersion. [2] The entire inversion process requires the gathering of seismic data, the creation of dispersion curves, and finally the inference of subsurface properties.
This radiative ground wave is known as Norton surface wave, or more properly Norton ground wave, because ground waves in radio propagation are not confined to the surface. Another type of surface wave is the non-radiative, bound-mode Zenneck surface wave or Zenneck–Sommerfeld surface wave .
