Course Learning Objectives: This course (18CSL67) will enable students to:

 Demonstrate simple algorithms using OpenGL Graphics Primitives and attributes.
 Implementation of line drawing and clipping algorithms using OpenGL functions
 Design and implementation of algorithms Geometric transformations on both 2D and 3D objects.

Descriptions (if any): --

The installation procedure of the required software must be demonstrated, carried out in groups and documented in the journal.

Programs List:

PART A

Design, develop and implement the following programs using OpenGL API
1. Implement Brenham‟s line drawing algorithm for all types of slope.
Refer:Text-1: Chapter 3.5
Refer:Text-2: Chapter 8

2.Create and rotate a triangle about the origin and a fixed point.
Refer:Text-1: Chapter 5-4

3.Draw a colour cube and spin it using OpenGL transformation matrices.
Refer:Text-2: Modelling a Coloured Cube

4.Draw a color cube and allow the user to move the camera suitably to experiment with perspective viewing.
Refer:Text-2: Topic: Positioning of Camera

5.Clip a lines using the Cohen-Sutherland algorithm
Refer:Text-1: Chapter 6.7
Refer:Text-2: Chapter 8

6.To draw a simple shaded scene consisting of a tea pot on a table. Define suitably the position and properties of the light source along with the properties of the surfaces of the solid object used in the scene.
Refer:Text-2: Topic: Lighting and Shading

7.Design, develop and implement recursively subdivide a tetrahedron to form 3D sierpinski gasket. The number of recursive steps is to be specified by the user.
Refer: Text-2: Topic: sierpinski gasket.

8.Develop a menu driven program to animate a flag using Bezier Curve algorithm
Refer: Text-1: Chapter 8-10

9.Develop a menu driven program to fill the polygon using scan line algorithm

PART B MINI PROJECT

The student should develop a mini project on the topics mentioned below or similar applications using Open GL API. Consider all types of attributes like color, thickness, styles, font, background, speed, etc., while doing a mini-project.
(During the practical exam: the students should demonstrate and answer Viva-Voce)

Sample Topics:

Simulation of concepts of OS, Data structures, algorithms etc.
Laboratory Outcomes: The student should be able to:
 Apply the concepts of computer graphics
 Implement computer graphics applications using OpenGL
 Animate real world problems using OpenGL

Conduct of Practical Examination:

 Experiment distribution
o For laboratories having only one part: Students are allowed to pick one experiment from the lot with equal opportunity.
o For laboratories having PART A and PART B: Students are allowed to pick one experiment from PART A and one experiment from PART B, with equal opportunity.
 Change of experiment is allowed only once and marks allotted for procedure to be made zero of the changed part only.
 Marks Distribution (Courseed to change in accoradance with university regulations)
o) For laboratories having only one part – Procedure + Execution + Viva-Voce: 15+70+15 = 100 Marks
p) For laboratories having PART A and PART B
i. Part A – Procedure + Execution + Viva = 6 + 28 + 6 = 40 Marks
ii. Part B – Procedure + Execution + Viva = 9 + 42 + 9 = 60 Marks
