Re: [Flightgear-devel] Matrox TripleHead2Go
Yes, John (LFSTech.com) has done some very nice work developing code that will do image warping and edge blending right inside FlightGear which is very cool. My understanding is we are waiting for Tim to review the changes and integrate them into the code base. Regards, Curt.

Re: [Flightgear-devel] Matrox TripleHead2Go
You may want to consider that not all video cards will work with this device. There is a program on their site that will check to see if your card is compatable or not (one of mine was not, and I'd not checked before purchasing the thing)! Slick if you can get it to work tho!! jj jj - This SF.net email is sponsored by: Microsoft Defy all challenges.
