Polygon Filling Algorithm - Raster Graphics and Clipping
In several graphics displays, this becomes essential to differentiate between different regions by filling them along with different colour or at least by different shades of gray. There are various methods of filling a closed area with a specified colour or corresponding gray scale. The most general classification demonstrated through following algorithms:
a) Scan Line polygon fill algorithm.
b) Seed fill algorithm./Flood fill algorithm that are additionally classified as:
(a) Boundary fill algorithm and
(b) Interior fill algorithm
We confine our discussion to scan line polygon fill algorithm, while we will discuss the others in briefly at the end of such section.
Question 1: (a) Describe what you understand by Rotoscoping in Graphic effects. Give details how Rotoscoping could be achieved in After Effects CS3. (b) Using one algorithm

Build a program that allows: 1. using mouse or keyboard to move around on a set of 16 control points; 2. modify the value (drag along x, y, or z) of a point; 3. display
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) =
Area Filling Algorithms Before we go ahead with area filling algorithms, a word about pixel addressing and object geometry. You know that line segments are discretized into fin
Rotation - 2-D and 3-D transformations Within 2-D rotation, an object is rotated via an angle θ along w.r.t. the origin. This angle is assumed to be +ive for anticlockwise rot
