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.
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.
28 Bézier patches (32 with the bottom) [1] Also called the "Newell teapot". One of the first models not to be measured. Cornell box: 1984 Cindy M. Goral, Kenneth E. Torrance, Donald P. Greenberg, Bennett Battaile at Cornell University: Originally meant to be compared to real-life setup to test physicality of simulated optics 5 quads, 1 light ...
A fractal landscape being rendered using the painter's algorithm on an Amiga. The painter's algorithm (also depth-sort algorithm and priority fill) is an algorithm for visible surface determination in 3D computer graphics that works on a polygon-by-polygon basis rather than a pixel-by-pixel, row by row, or area by area basis of other Hidden-Surface Removal algorithms.
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.
Each serial bus is actually a part of the Video Bus, which has a bandwidth of 1.2 GB/s. Four Image Engine "cores" are contained on an Image Engine ASIC, which contains nearly 488,000 logic gates, comprising 1.95 million transistors, on a 42 mm 2 (6.5 by 6.5 mm) die that was fabricated in a 0.35 micrometre process by VLSI Technology.
In mathematics, Fresnel's wave surface, found by Augustin-Jean Fresnel in 1822, is a quartic surface describing the propagation of light in an optically biaxial crystal. Wave surfaces are special cases of tetrahedroids which are in turn special cases of Kummer surfaces. In projective coordinates (w:x:y:z) the wave surface is given by
On older vectorscopes that use cathode-ray tubes (CRTs), the graticule was often a silk-screened overlay superimposed over the front surface of the screen. One notable exception was the Tektronix WFM601 series of instruments, which are combined waveform monitors and vectorscopes used to measure CCIR 601 television signals.
