Hi,

Just to understand how setProjectionMatrix works, say, I need to set X-Focal 
length of viewer's camera to 1000 and Y-Focal length to 600. 
Also i need the Camera to be translated by x by 0.5 to the right and y by 0.7 
down.
What matrix m should i pass to viewer.getCamera()->setProjection(m) to achieve 
that? Or should I use some other function?


... 

Thank you!

Cheers,
Igor
