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.
Distinguish between convex and concave polygons? If the line joining any two points in the polygon lies totally inside the polygon then, they are called as convex polygons. If
What is rotation? A 2-D rotation is completed by repositioning the coordinates with a circular path, in the x-y plane by making an angle with the axes. The transformation is g
