Computer Graphics

Objectives: Main objective of the course is to familiarize students with basic computer graphics pipeline and processing within each block of the pipeline using OpenGL. Students will be able to implement different graphics techniques to create animation of realistic looking images and videos commonly used in movies, games, television commercials.
