Purposes:

• Introduce students to all aspects of computer graphics: hardware, software, applications
• Understand the basic concepts underlying computer graphics
• Gain experience with at least one graphical application programming interface (OpenGL)
• Carry out a large programming project of your choice
• Use (and enjoy) the knowledge gained in previous CS/CE classes

Prerequisites:

• Good programming skills in C equivalent to CS 351 or EECE 331/332
• Data structures equivalent to CS 251
• Trigonometry and simple linear algebra

Grading:

• Required projects (3): 50%
• Term project: 50%, students select term project from a list or propose their own.

Computing Facilities and Projects:

Students can do the required class projects using OpenGL on UNM workstations or their own PCs.

• OpenGL is available free for PCs under Linux, Windows and the Mac.
• There is a variety of other software and machines available for the term project including PIXAR's Renderman, Maya, and Khoros. Projects using computers in other locations are possible.
