Re: [Flightgear-devel] simulating camera output during flight
Start fg with --jpg-httpd=port, then you should get a screenshot in your browser, since it's a simple request you could code the http get request in you application, not sure if it's fast enought for realtime. Is really fast. I'm using the --jpg-httpd option to interface FlightGear with a ground station developed under C++ Builder compiler and I can receive almost 20 frames by second in my local network. But to run with this speed you will need get the CVS version of FlightGear because I think that latest release, 0.9.10, this feature was not optimized like CVS version.

I would like to use FG to have a nice graphic interface but mainly to have a realistic sourrounding for my helicopter. I'm sure that it's possible to impose to a FG helicopter model positions and euler angles calculated with an external engine (like mine) but i'm not sure if it is possible to use run-time the rendered images originated from a view point! I have the need to handle the images run-time to elaborate them with vision algorithms and to evaluate the controller response that pilots the helicopter. I see in the manual that it's possible to save a movies during the flight for post-process purpuse but it's not useful for my target because it's not run-time. Does anybody know if it possible to do something similar I need? I'm a newbie using FG so I ask you sorry if this is a dumb question! Thank for helping. Domenico - Take Surveys. Earn Cash.

Re: [Flightgear-devel] tutorial news
* AJ MacLeod -- Tuesday 20 March 2007: I'm looking forward in particular to the lookat thingy, that should be a very nice touch... Yeah, it is. :-) That's now implemented and already added to the Lightning's startup tutorial. It's animated such that the pilot's view is directed at the respective controls. m. - Take Surveys.

Re: [Flightgear-devel] simulating camera output during flight
In fact, this feature was modified by me, and accepted by Flightgear team, almost 6 months ago and after this no Flightgear version was released (I think), then you should consider get latest Flightgear CVS version to get this improvement (because old implementation was really slow). Note if you are using this on a local network it would be trivial To change the code to return the data directly bypassing the compression/decompression overhead, this should speed things up If your network can handle the bandwidth :-) Yes, your suggestion is fine, but I don't think that our team will try do something like this. :.)

Norman, The changed revision is 1.7 for jpg-httpd.cxx file and 1.4 for jpg-httpd.hxxfile. jpg-httpd.cxx http://cvs.flightgear.org/cgi-bin/viewvc/viewvc.cgi/source/src/Network/jpg-httpd.cxx?revision=1.7view=markup jpg-httpd.hxx http://cvs.flightgear.org/cgi-bin/viewvc/viewvc.cgi/source/src/Network/jpg-httpd.hxx?revision=1.4view=markup Check the HttpdImageChannel::foundTerminator( void ) method modifications. Basically the performance was improved and a memory leak was fixed too. Thanks by original implementation of this feature, is really useful.

Re: [Flightgear-devel] simulating camera output during flight
In time, Another improvement was transfer complete (variable size) content of flightgear screen and the old code did transfer just a static size of screen (400,300) pixels.
