Retrieving Coordinates after rotations
I'm rotating my camera using glRotatef, this work's fine, but my problem is how can I get the new coordinates.
For example I draw a line, after I make a rotation. If I draw a new line, they're coordinates is wrong. But if I rotate the camera to the original angle, the line is in correct position.
How can I make this tranformation?
Thank´s for the moment.
Re: Retrieving Coordinates after rotations
you want to save the original modelview matrix and restore it after you draw the primitives.
