Hey! I''ve been working with making an interactive viewpoint in my OpenGL stuff. I chose to take quite a different approach than in Lesson 10. I use gluLookAt to change the viewpoint position. Anyways... I currently have bound keys to the movement functions, but I would like to be able to move around using the mouse (not the buttons on the mouse). Where can I find information about how to use the two axes of the mouse? Thanks.

There''s a really simple way to use the mouse for looking around in Lesson 23, hehe, it''s like a few lines.

take a look at this

if that is what you want, just look for the code of Gavin Bell and use it.

Hope this helps!
