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.
For orthographic parallel projection: glOrtho(left, right, bottom, top, near, far); glOrtho2D(left, right, bottom, top); Here left, right define the x-direction ex
2D Line Segment Generation A digitally plotted line is basically an approximation of infinite number of points on an abstract line segment by only a finite number of points on
