Hi there,

I am trying to replicate the Performer culling and LOD switching. Performer
uses a global scale factor to adjust LOD switch ranges in a non-normalized
channel setup (1024x1024 pixel single channel, 45 degree fov, etc). I would
like to know how to calculate this scale factor. Can someone give me some
hint, like the equation? Thanks very much.
