These are some libraries that I know and love.
- OpenGL – Cross-platform hardware accelerated graphics are your friend. The NeHe OpenGL tutorials are great, and apparently so is the red book. Distributing Python OpenGL apps with py2exe
- ARToolkit – The famous Augmented Reality Toolkit designed for drawing virtual imagery on top of a live video feed. Uses printed markers (black squares) to determine the marker orientation relative to the camera. GPL and theoretically there is a closed source version. C and Java versions.
