| | Vision Command and source compatibility testing

A few months ago I attempted to discover how VC was accessing the Lego cam. My theory is that VC only cares what driver is being used either due to contract with Lego or because VC may rely heavily on the Logitech QuickCam SDK. Here's what I've (...) (23 years ago, 29-Apr-02, to lugnet.robotics)
