[Flightgear-devel] Current Elevation

2002-05-02 Thread Sam Varner
I want to get the elevation of the ground for points other than my current location. I suppose I could do this by moving to a new location and calling scenery.get_cur_elev(). Is there a better way? If not, what operations will update the output of FGScenery::get_cur_elev() in the most

[Flightgear-devel] Coordinate Systems

2002-04-17 Thread Sam Varner
My model uses a rotation matrix to specify its orientation. But it looks like FlightGear wants Euler angles. Is there funcitonality for converting from one to the other in FG or PLIB? Also, I'm using a cartesian vector for position. Is there a good way of converting to geocentric coordinates?

I just made my first, um, flight dynamics model for Vamos. It doesn't do anything useful yet. But I was wondering if anyone had tips on reducing compile and startup times. ___ Flightgear-devel mailing list [EMAIL PROTECTED]

Hi folks, I got in touch with Curt a few days ago to try to get some help on making Windows binaries for my project (Vamos Automotive Simulator http://vamos.sourceforge.net). He invited me to join the list to try to recruit some help. So drop me a line if FlightGear isn't keeping you busy
