4	Fundamentals of Animation Techniques:	4.1 Animation sequence 4.2 Key-frame and parameterized systems   4.3 Morphing and simulating acceleration	[3]
5	Introduction to Web Graphics Designs and Graphics Design Packages:	5.1 Introduction to graphics file formats 5.2 Principles of web graphics design – browser safe colors, size, resolution, background, anti-aliasing 5.3 Type, purposes and features of graphics packages  5.4 Examples of graphics packages and libraries	[4]
Practical:			[45]
As a part of the laboratory exercise, the students should implement all the algorithms studied in different chapters. At the end, students are required to integrate the codes they have written in earlier practical sessions to create a small project.   The lab contains few sessions dedicated to introduce the students to some of the popular professional graphics packages and CAD packages and explore their features. The course/lab instructor recommends packages to use.  Some algorithm implementation sessions may include: a.     Implementation of DDA and BLA  b.     Implementation of circle and ellipse drawing algorithms  c.     2D transformations d.     Projections e.     3D transformations.
