I notice they mention using quaternions in the abstract but it is probably easiest to grasp a Matrix formulation first http://ocw.mit.edu/13/13.49/f00/lecture-notes/all-Z-H-3.html Using a quat is a bit more 'elegant' but is pretty much the same thing here is a *classic* explaining the relationship that is esp relevant to FlightGear http://www.movesinstitute.org/~zyda/pubs/Presence.1.4.pdf AFAIK Most all prediction and extrapolation is done with a kalman these days lots of *good* stuff here and also at the MIT site linked above http://www.cs.unc.edu/~welch/kalman/ Norman > (It's $19 from the site with out a web account). > > Mike > > On Wednesday 15 January 2003 10:39, Alex Perry wrote: > > I'll go have a look ... > > > > > Message: 3 > > > Date: Tue, 14 Jan 2003 20:14:15 -0600 > > > From: Mike Bonar <[EMAIL PROTECTED]> > > > Subject: Re: [Flightgear-devel] IPC communication for FlightGear > > > To: [EMAIL PROTECTED] > > > Reply-To: [EMAIL PROTECTED] > > > > > > Anyone have an IEEE membership? > > > > > > http://www.computer.org/proceedings/ds-rt/1053/10530045abs.htm > > > > _______________________________________________ > > Flightgear-devel mailing list > > [EMAIL PROTECTED] > > http://mail.flightgear.org/mailman/listinfo/flightgear-devel > > > > -- > Linux 2.4.19, P4 1.5, 512MB, Geoforce 3 > Trim for 60, carb heat on, fuel on, electricals on, throttle open one quarter, > turn to start... > > _______________________________________________ > Flightgear-devel mailing list > [EMAIL PROTECTED] > http://mail.flightgear.org/mailman/listinfo/flightgear-devel > _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
