[simpits-tech] Visuals questions...

[Sean Galbraith]

Gidday team,

I am still working away on my TA-4 Skyhawk sim, although it appears 
that it may take till the next ice age before it's done...
Anyway, I have been thinking of the options for visual systems, from 
the basic; single front/back projected, through to complex curved 
screen, multi-projector setups.  I am quite keen on more than a 
single view setup, but the operating costs of 3 projectors, for a 
home cockpit, are a bit high (and I am cheap...).  I have been 
looking at the idea of 3 large CRT's running through a Matrox 
Triplehead2go, with suitably sized fresnel lenses in front, aiming to 
produce a reasonably seamless image.
Has anyone had experience with this sort of setup?  I have seen 
plenty of sims using a single large CRT + Fresnel, but none using 3.
As I see it, the challenges are finding the right size lens, plus 
matching the perceived images on the 3 screens.
I'd be interested in thoughts, ideas and suggestions....
