Hi Ricky, There isn't a concept of focal length with OpenGL or OSG cameras. Focal length is only relevant when you use depth of field effects which the OSG doesn't provide out of the box - it's something you have to implement yourself with an appropriate slave camera or render to texture camera

[osg-users] parameters

2010-08-05 Thread Ricky Flintoff
Hi, I wanted help with setting these five camera parameters: focal length, f, the location of the image in pixel coordinates (o_x, o_y), the effective pixel size in the horizontal and vertical direction (s_x, s_y)? How can I set these is osg?? Thank you! Cheers, Ricky --
