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.
Draw and explain the diagram of a Raster scan system with a display processor. Explain each unit of the diagram.

What is Aspect ratio? The ratio of vertical points to the horizontal points essential to produce length of lines in both directions of the screen is known as the Aspect ratio.
Orientation Dependence - Modeling and Rendering The outcomes of interpolated-shading models are dependent of the projected polygon's orientation. Because values are interpolat
