Output Primitives and Geometric Transformations
You learnt how some basic geometric objects such as line segments, circles, ellipses and other curves are processed for plotting on a display unit. In most of the graphics packages you will find that polygons are also used as standard output primitives. Filled polygons with single solid color (or other alternatives for filling the interior) are provided as shape primitives.
Bresenham Line Generation Algorithm for Positive Slope (BLD algorithm for positive slope (0 - If slope is negative then utilize reflection transformation to transform the
1. By using Digital Differential Analyzer algorithm draw line segments from point (1,1) to (9,7). Ans. We see that the usual equation of the line is specified by: y = mx+c
Remember in polygonalization of the surface, following rules must be followed. Any two polygons (i) share a common edge, (ii) Share a common vertext, (iii) Arc disj
