With a perspective projection matrix and camera system already in place, I have a scene with a small jet fighter flying high over a wide and deep canyon with many cliffs and rocky surfaces; these are all being rendered as wireframes for now. The camera is following the ship which is flying entirely on the X-Z plane.
Right now, when the ship moves by some amount r, the entire canyon moves by that same amount in the opposite direction. I want to have parts that are further away from the camera to move slower, so I need parallax.
If I were going to implement parallax, in which part of the rendering system would it go, the projection matrix?
Below is a screenshot of the game as it is. The ship is moving forward and about to pass through some rocky crags.
