Functioning of hardcopy devices and Output primitives
1. Functioning of hardcopy devices-laser printers and dot matrix printers, plotters.
2. Output primitives: Graphics programming packages provide basic geometric shapes such as line segments, circles, ellipses and other simple curves as building blocks for defining more complex structures. These are known as output primitives.
1. What is the purpose behind the Staircase effect? Ans. The approximation concerned in the calculation for finding of pixel position concerned in the display of lines and th

Cohen Sutherland algorithm Point clipping is very simple. All you need to check is whether a point is inside the window extremes in x- and y-directions. For line clipping sev
Illustration: Find the normalization transformation N that uses the rectangle W (1, 1), X (5, 3), Y (4, 5) and Z (0, 3) as a window and also the normalized device screen like the

Essentialily of Computer Simulation You may want to understand why to do simulation? Is there any one way to perform the tasks? To converse these matters lets briefly discuss
Exceptional cases - Orthographic Projection 1) We have an Orthographic projection, if f=0, then cot (β) =0 that is β=90 0 . 2) β =cot-1 (1)=450 and this Oblique projec
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) =
