For assignments that use graphics hardware, we recommend using the UTCS linux machines in the basement of Taylor Hall that are named after ship parts (e.g. capstan). These machines have NVIDIA GeForce FX 500 graphics cards.
The CS department also has a WindowsXP instructional lab (unfortunately with older graphics cards) in Painter 3.12. For your final project, you may use these machines if you wish, which allows you to use DirectX instead of OpenGL. For the final project, you can also use any other personal or research-group desktop machine, as long as the machine is located in the Taylor or ACES buildings on demo day so that the TA can easily travel to your machine.
