So I am prototyping a 3rd person camera this week as part of a game project I am on and I wanted to see if anybody who has done one before knows of what pitfalls and problems I can expect so I can avoid problems and come up with solutions.

I want the camera to follow a Legend of Zelda type camera and allow for me to specify points of interest in the scene. If the camera is near a point of interest it should gravitate towards it, but not necessarily look right at it.

I would also like the camera to apply the Rule of Thirds if possible.

I would just like to know if there are any gotchas that I may be overlooking, and any possible solutions. Thanks.
