MAT 594CM S2009
Angus Forbes & Wesley Smith, Instructors
This course provides a foundation for computing in multidimensional spaces, investigating the synthetic and generative potentials of elementary geometric constructs. Subjects covered will include vector and matrix math, space partitioning, collision detection, and kinematics. We will focus both on mathematical foundations and practical computational techniques for creating real-time 3D graphics via OpenGL.
Students will produce a number of investigations into the topics covered, culminating in a final programming project. No prerequisites are required, although some basic knowledge of programming is assumed. The course will consist of one lecture class and one lab class per week.
Lab sessions will be an opportunity to synthesize the lectures and get your hands dirty with the various concepts and algorithmic techniques. All lab work will be done in OpenGL on the platform of your choice. Suggested platforms are GLUT-Muro, OpenFrameworks, LuaAV, and Processing-JOGL.
In addition, lab sessions will be used to teach advanced software design techniques for real-time multimedia from a holistic perspective. In orther words, we will be working not just on the coding itself, but also on the toolsets that support effective coding practices and workflow. Students will be required to manage their code with a source code manager (SCM). The MAT servers are currently equipped with Subversion (SVN), which is the recommended SCM, see Introduction to Subversion. If you're on Windows, the recommended SVN client is Tortoise Subversion.
