'3D Games', by Watt and Policarpo, has a section on 'practical bezier technology for games' that basically lays out the Q3 system.

Also, check online for the source code to the following Q3 level-viewing engines: cake, Titan, and Diesel. Each should have code for evaluating Q3 bezier patches.

Or, find any tutorial on regular quadratic bezier patches, and then consider each Q3 patch as an nxm array of regular patches. There's some work to be done there, but it's not insurmountable.

Let us know if you have any other questions.
