Course Outcomes: The student will be able to :

 Design and implement algorithms for 2D graphics primitives and attributes.
 Illustrate Geometric transformations on both 2D and 3D objects.
 Apply concepts of clipping and visible surface detection in 2D and 3D viewing, and Illumination Models.
 Decide suitable hardware and software for developing graphics packages using OpenGL.

Question Paper Pattern:

 The question paper will have ten questions.
 Each full Question consisting of 20 marks
 There will be 2 full questions (with a maximum of four sub questions) from each module.
 Each full question will have sub questions covering all the topics under a module.
 The students will have to answer 5 full questions, selecting one full question from each module.
