Greetings, I am working on a virtual bronchoscopy (a scope that goes in the airway) project in unity. I've been building it for awhile so I thought I'd post it and get suggestions. You can navigate around until you get to certain points where the bronchus narrows and the scope can go no further. You can rotate the scope (yourself) as well. I will be building more functionality in later. http://brodel.med.utoronto.ca/~leslie/bronchoscopy.html Bugs I still need to fix: -When you rotate more than 90 degrees, your left and right reverse. -Sometimes you get stuck and can't back up. -the GUI text looks pretty bad. Controls: w/s - forward/backward x/z - rotate CW/CCW a/d - rotate lung model Any suggestions appreciated!
