Assumption regarding to the Digital Differential Analyzer Algorithm
The line generation by DDA is discussed merely for the first Quadrant, whether the line lies in the other quadrant then apply respective transformation usually reflection transformation, thus it lies in first Quadrant and then proceed along with the algorithm, as well make intercept Zero through translational transformation so (xi, yi) solves to (xi, mxi + c) or (xi, mxi) and related simplification arises for the other cases of line generation. The idea and application of transformations is discussed in further course.
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

Illustration of a Clipping window ABCD is placed as follows: A (100, 10), B (160, 10, C (160, 40), D (100, 40) By using Sutherland-Cohen clipping algorithm determine the vis
Explain the merits and demerits of Plasma panel display. Advantages: Refreshing is not needed. Produce a very steady image free of Flicker. Less bulky than a CRT.
Key Frame Systems - computer animation This method is for low-level motion control. In fact these systems comprise languages that are designed simply to produce the in-between
Properties of Bezier Curves - modeling and rendering A very helpful property of a Bezier curve is that it always passes via the first and last control points. Such the bounda
Example: Exemplify the Bresenham line generation algorithm through digitizing the line along with end points (20, 10) and (30, 18) Solution: m = (y2 - y1)/( x2 - x1) =
