What is Raster Scan Display
A raster scan display device using CRT on the other hand directs the electron beam across the screen, one row at a time from top to bottom. In a raster scan display device, the screen is assumed to consists of a two-dimensional matrix. Remember that the term raster was used for a 2-D matrix. Each point of the screen corresponding to a matrix element is called pixel (picture element) as shown in Figure
Bezier curves: Theses are special polynomial curves expressed using Bernstein polynomials. Spline curves are simple extensions of Bézier curves composed of two or more polynom
GRAPHICS: It is one of the core elements of any multimedia application. We all have heard a well-known saying as "one picture conveys a message of 1000 words", hence without
What is the full form of IGES?
General Perspective transformation with COP at the origin Here we suppose the given point P(x,y,z) be projected like P'(x',y',z') on the plane of projection. The center of pro
Filled-Area Primitives Filled-area primitives are one of the most important types of primitives used in Computer Graphics. Basically filled-area primitives are meant to fill
Algorithm (scan-line): For each scan line perform from step (1) to (3). 1) For all pixels on a scan-line, arrange depth [x]=1.0 i.e. max value and Intensity [x] = background
Important points about the Surface of Revolution a) if a point on base curve is given by parametric form, that are: (x(u), y(u), z(u)) so surface of revolution regarding to th
Question: (a) There are 3 main industries of drawing style and it has become a phenomenon. It was inspired by internationally diffused cartoons, comic strip books and since the
What is scaling and shearing? The scaling transformations alters the shape of an object and can be carried out by multiplying every vertex (x,y) by scaling factor Sx, Sy where
Algorithms for filled-area primitives These algorithms are classified into two categories (i) Scan line algorithms (ii) Seed fill algorithms.
