Dear Marc

I don't have any special technic and i just wanna find a way to have
a undistorted scene on a cylindrical screen with a ordinary projector.
of course I prefer to do that by software modification not by hardware
for example i guess there should be a matrix if i used it in my code (directx)
i will have a undistorted scene, but hardware ways may be used too.
Do you know a special lens for that?

Regards,
Hamed.
