picking glOrtho vs gluPerspective - rhiannon - Jun 6, 2005 02:20 PM
Recently I decided to have the option to switch to a glOrtho when viewing a model, from gluPerspective, when I make this switch my picking code does weird things... It still picks and processes hits but they are off, they don't line up at all. I'm a noob so it's probably something simple. I just replace the gluPerspective calls with similar ones to glOrtho, both in the real viewing and in the picking view. It works fine in gluPerspective btw. Any ideas?
