Can anyone help? I'm having some issues with regard to Field of View.  

Essentially I want to change the fov of my camera from what i believe is the default of 60 degrees (Pi/3) to 90 degrees(Pi/2). Unfortunately there is no option to adjust fov in the camera() function.  Essentially, I am trying to line up screens that are placed at right angles to each other and I just can't get them right.  I tried using the perspective() function but this is not really the answer and anyway it still doesn't get them lined up right.  

Is the OCD library the only answer ? or does anyone know of a way that I can simply adjust the fov of the standard camera?
