  what should be the typical value of field of view for perspective projection if we want to implement flythrough using open gl???   
Quote:what should be the typical value of field of view for perspective projection if we want to implement flythrough using open gl???A horizontal field of view of 90 is pretty common. Assuming an aspect ratio of 4:3, this equates to a vertical field of view of about 72 degrees, IIRC (if you're using gluPerspective(), you'll need the vertical rather than horizontal field of view).
