Re: [Flightgear-devel] Projection system question
Hi. Two things: First, keep us posted of your progress :) I am also working on simulator stuff at our aviation club, so this kind of stuff is interesting to follow. Another thing that comes to my mind is a spherical door projection example I remember seeing on README.multiscreen (or it was one other file in the docs/ dir in flightgear sources) - Did you check that example out, did it not do what you needed? Unfortunately I am also just looking into all this, so I cannot be of more help, but I remember trying that one, and it warped the display to a circle and the perspective was all curved, so maybe it could be something useful? Anyway, thanks for posting the link, that kind of setup looks very interesting, given it uses just one projector. Might work for us also.. /Tuomas On 12.2.2012 22:59 Roy Caligan wrote: Hi everyone, I've been speaking with some of the folks on the FG forum about a problem I'm having, and I was recommended to contact this group for some possible help.
