I have taken the principles from this post and applied them to the camera in my Papervision3D scene. By moving the slider you can control the position of the camera in a nice smooth motion. This opens a lot of possibilities, and solves a lot of problems. based on this basic system, controlled camera movement is quite easy. I am going to refine this and release it as ActionScript class, so watch for that. In the mean time, enjoy!
Drag the slider to move the camera.
