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.
(a) Differentiate between the following compression algorithm: 1. Shannon -Fano Algorithm and 2. Huffman Encoding (b) A statistical encoding algorithm is being considered

Important Points about the Curve segment - properties of bezier curves Note : if P (u) → = Bezier curve of sequence n and Q (u) → Bezier curve of sequence m. After that Co
Find the normalization transformation N, which uses the rectangle W(1, 1); X(5, 3); Y(4, 5) and Z(0, 3) as a window and the normalized deice screen as viewpoint.
Sutherland-Hodgman Algorithm Any polygon of any type of arbitrary shape can be explained with the assist of some set of vertices connected with it. While we try to clip the po
Other curves - parabola and hyperbola Conic sections such as parabola and hyperbola are used in many instances such as in motion planning along a trajectory or in modelling the
