I don't imagine it would take too much to get it to compile see http://prettypoly.sf.net Norman --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

I hope you decide to stay - I've already pointed out some of your great looking models (from the CSP forums) to others here :-) I am a 3D modeller for Strike Fighters : Project 1 (check out http://www.column5.us, there is a F/A-18 model I made) using blender. I am willing to build many models for FlightGear but I can see two issues : * Blender does not allow to change easily the transforms in the scenegraph (i.e. hard to orient axis) * Using the XML configuration file to adjust animation can be pretty clumsy requiring a long trial error process. I am also building a model for fgfs, although to rather lower artistic standards than yours... but to be honest, most of the animation is actually not too hard to do in our XML system. There are one or two exceptions I've come across in gear animation, but aside from that with one or two little hints and a bit of practice it mostly becomes fairly straightforward. You not be aware of Melchoir's fgfs animation exporter for blender (from http://members.aon.at/mfranz/fgfs_animation.py - also see http://members.aon.at/mfranz/flightgear/blender-textured-lights.html) which can do some of the XML legwork for you, although not quite to the degree you are looking for. Also courtesy of Melchoir I hope we might see a morph type animation soon which might make some currently difficult things easier. I would like to know if it could be possible to start a project for a plib application allowing to set up animations, rotating an moving axis in a scenegraph and exporting the corresponding animation in the xml config file. That would make 3D models *much* more easy. If anybody is interested or knows how to setup such a project I would be happy to join Aside from the script above I don't know of such a project yet... There is talk of people wishing to move fgfs to OSG which might make such a thing much easier, but that's some way into the future if at all. In the meantime, if you need advice or hints on using our current animation system, the IRC channel is often a great source of quick pointers...

RE: [Flightgear-devel] Modelling tools
I am also interested in the modelling of jet engine. I've been looking into the problem for quite some time and have darkened many pages of equations in order to find a model that could meet my expectations. What I would like to achieve would be the following - Engine stall and surge simulation - supersonic behavior (intake + nozzle) - arbitrary number of spools - adequate computation of display parameters (N1, N2, Fuel flow, EGT ...) - adequate engine response I would like to know what is the status of this modelling today in JSBSim and with whom such matters could be discussed Regards FT Hi, FT: You could discuss this on the JSBSim list, or here. Right now, we have a turbine model that seems to work pretty well, but you are welcome to take a look at that and either suggest/work on specific improvements, or see how the interfaces work and try writing one yourself. Note that one limitation that makes the task a bit harder is the generalization so that it works for many specific engines. And the specification/configuration file must be designed with publicly available (or deducible) information in mind. Right now we don't use a nozzle, or inlet. Some discussion on that would be interesting. Jon --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
