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.
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.
[2] This is a divide and conquer algorithm with run-time of () [dubious – discuss], where n is the number of polygons and p is the number of pixels in the viewport. The inputs are a list of polygons and a viewport. The best case is that if the list of polygons is simple, then draw the polygons in the viewport.
Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.

Part A is a preliminary screening test. There are about 50 questions in this part having negative marking. Correct answers carry +2.0 marks and wrong answers carry -0.5 marks (negative). Each question in this part checks general knowledge and awareness. Part B is evaluated for those candidates who are short listed in the screening test (Part A).
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 .
The MDA was based on the IBM System/23 Datamaster's display system, [2] and was intended to support business and word processing use with its sharp, high-resolution characters. Each character is rendered in a box of 9 × 14 pixels , of which 7 × 11 depicts the character itself and the other pixels provide space between character columns and lines.
