OpenGl - Camera rotation
WHat I''m trying to do is have a model of the solar system. I have the 9 planets and they rotate around the sun. I now want to add camera movement so that I can move in and around the planets, and also so I can just rotate the view so that instead of looking at the planets straight on horizontally (so that they rotate around the y axis in front of me) to one where I am on top of the planets, looking down.
Here is the rendering code, where would I put in the camera transformations?
