[Flightgear-devel] event: Flightgear talk in Santa Monica, CA, USA
The Coastal Los Angeles IEEE Section Computer Society Chapter presents ... Introduction to the FlightGear Flight Simulator September 12, 2006 at 7:30pm Alex Perry, Google, 604 Arizona, Santa Monica, CA 90401 FlightGear is a GPL open source flight simulator that runs on a wide range of platforms including Linux, MacOS and Windows. The simulation itself, the worldwide scenery and the aircraft models are free to download from www.flightgear.org and its mirrors. This talk will provide an introduction into the project, its goals, getting started, and a demonstration of the system in action.

Re: [Flightgear-devel] Bug in mp-visibility of planes?
I commited a fix for this specific problem, as diagnosed by Maik. I will
look at Olaf's code later.

But there's still one STEER input axis per gear, which was the source of the question, I believe. Yes, you can obviously sum multiple property inputs to that axis.

If it is KSFO, use the demonstartor setup. (but I don't know, if this is possible in the .xml file). Maik - Using Tomcat but need to do more? Need to support web services, security?

I had a saitek x45 - excellent stick, just worked, didn't even need calibrating. Sadly after a few years of fairly heavy use it's died and I've not had chance to replace it with anything similar yet. -- Jon Stockill [EMAIL PROTECTED] - Using Tomcat but need to do more?
