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.

What is a dot size? Dot size may be explained as the diameter of a single dot on the devices output. Dot size is also known as the Spot size.
Three dimensional display methods: Among the simplest three dimensional surface representations are the polygonal surfaces. A polygonal surface is described by vertices
Question 1: (a) Once a selection is made, what area of the image can be edited? (b) What is the purpose of saving selections? (c) How can you move a selection while you a
Points and Lines - Graphic primitives In the previous section, we have seen to draw primitive objects; one has to firstly scan convert the objects. This concern to the operat

Presentation Graphics The instant you are going to represent yourself or your product or company or research paper and so on. Only standing and speaking is fairly ineffective.
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
