Re: [Flightgear-devel] least squares code

2009-10-18 Thread wim van hoydonck
You might want to give kst [1] a try, which includes a plugin for weighted least-squares data fitting [2]. imho, kst is the easiest way to plot data in real time (with or without filters), and works very good with flightgear csv output (with a little bit of javascript). Wim [1]

Hi all, I bought a new laptop (intel core 2 duo with nvidia graphics card) and I'm having problems with the (too high) frame rates (fg/osg). Whenever I look outside in fg, the framerate skyrockets to values around 300 which induce stutter in the simulation. A (partial) solution would be to

I just looked at the data for the ch47, and I think there are some values that could/should change, based on the data for our own chinook flight dynamics model (for the CH47D) rotor parameters: blade mass - 111.6 [kg] omega - 23.562 [rad/s] (=225 rpm) - value much too high in yasim config file

Hi there, That's because you have to install the patched OSG version and not the one from the AUR (I suppose you did that). See here: http://wiki.flightgear.org/flightgear_wiki/index.php?title=OpenSceneGraph Or if you do not want to run the osg version of flightgear, do a cvs update
