Enjoying the evening reading, Texturing and Modeling: A Procedural Approach.
Bantered back and forth with one of the developers at Eye Control Technology over email earlier(the people who sell the TrackIR). They're going to release some more information on their website tonight about the firmware, general questions that everyone is asking(including me). It looks fairly easy, from the kernel source I've looked at, to write a driver that loads the firmware and reconnects to the real device. I've already got one on order, I hope I get it soon so I can start hacking on a driver. It will be the first kernel driver I've really sunk my teeth into, but I feel confident about being able to do it(unlike working on the 3com HomeConnect, which completely shattered my confidence in that device, not being able to work out the format of the color images). My goal is to get the driver to a point where I can write an app that loads a mesh of a face(or possibly a Quake3 model's head) and map vertices of the mesh to reflector dots on my face.
Pet peeve: People who feel the need to correct everyone's grammar and spelling because they couldn't spell Mississippi until high school.
