Welcome to

CS 4/57101 Computer Graphics

Goal:The goal of this course is to provide anintroduction to the theory and practice ofcomputer graphics.The course will assume a good background inprogramming in C++ and a background inmathematics including familiarity with thetheory and use of coordinate geometry and oflinear algebra such as matrix multiplication.

Components of Course

z There will be three components to the coursey You will gain an understanding of the fundamentals

of computer graphics through study of the thetechniques, algorithms and hardware used incomputer graphics.

y You will gain experience in the techniques involved inlow level computer graphics programming such asthat used to create computer graphics packages(such as OpenGL).

y You will use the industry standard based OpenGLlibrary in several programming projects illustratingthe theory and practice of programming computergraphics applications.

Assesment:

z Midterm Examination : 30%Final Examination : 30%Assignments (2 to 6) : 40%

z Notes:y Assignments will primarily be programming

assignments requiring implementation of applicationsemploying the theory covered in the lectures andbooks. There will however be some threoreticalhomeworks and questions as well. Students arereminded that completion of both theory andprogramming parts of the homework are necessaryto achieve a good grade.
