Hardware Concept in Computer Graphics- Mouse and Pointing Devices

Mouse play a very important role in development of Computer Graphics and to implement graphics in the computer system. Mouse is a pointing input device that points out item(s) by cursor. The cursor can be move from one position to another, this movement of cursor is due to the movement of mouse in the plane …

Write a program (WAP) to draw a circle using Mid-point Algorithm

Although Bresenham’s algorithm is based upon integral operations only and is much faster than other algorithms, yet there is one drawback of this algorithm. This method is not uniformly applicable to all sorts of conics. For eg, for the ellipse drawing procedure, we need to treat two different regions in the first quadrant differently. This …

Drawing a line using DDA(Digital Differential Analyzer) Algorithm

DDA Algorithm The Digital Differential Analyzer DDA is a scan conversion line algorithm based on calculating either the difference of y or x ie ?y or ?x. The pixel positions are calculated initially- uses raster characteristics so that appropriate increments are applied in the x or y direction to step to pixel positions along the …
