Students implement class projects with the C and/or C++ programming language, using the computer systems available in the Computer Science Instructional Facility. The programming projects for this class are chosen to enhance the lecture material in the course.

Goals: Students will: (1) learn the basic principles and problems of computer graphics; (2) learn mathematical background to understand and implement these basic principles; and (3) learn the underpinnings of the implementation of computer graphics modeling and rendering systems.

Textbook:
Angel, Interactive Computer Graphics A Top Down Approach With Open GL, Addison- Wesley, 2005

Computer Usage:
Students implement their term projects with the C and/or C++ programming language, using the computer systems available in the Computer Science Instructional Facility.

Programming Projects:
The programming projects for this class are chosen to enhance the lecture material in the course.

Engineering Design Statement:
The individual student taking this class will design and document a complete computer graphics modeling and rendering system that contains (1) a complete transformation/clipping package, (2) an elementary modeling package which will enable construction of complex scenes, and (3) a visible surface determination package. The design of the system is embodied in the “milestone” papers that are required in advance of the project deadlines. The students must design and implement the components of the system. Examinations also include questions based on design components of the course in addition to formal concepts.

Visual Literacy

Justification for Visual Literacy: This course teaches students to understand and interpret patterns of visual material. Its assignments also give students techniques for recording and conveying visual evidence. Students are tested throughout on their ability to interpret visual data accurately and observantly
