Okay, for my physics project, I have to analyze a video game and write about the physical impossibilities in the game. Simple enough. I want to do the project on halo 3. I thought that it would be easier due to the recording and replay capabilities. I would preform an action such as throw a grenade or whatever, watch the replay, move to a good position, and record the action with my camera. Then I would upload to my computer and use logger pro (a graphical analyzer) to tell me the equation of the graph. Understand so far? Now the problem. Halo is a 3d game, and that adds the problem of perspective distortion. If the object moves 1 inch to the left directly in front of me, it will not look like it moves the same amount as if it moved 1 inch to the left a mile to the side. The distance is the same, but on the television, it would show much less movement, and therefore the graphical analyzer would not be as great as possible. I can watch the actions from multiple viewpoints, but I still am at lost as to the solution. Anyone know of a way to solve my predicament? Any questions that you may have (i.e. i was not clear on something) can be posted here. PLEASE HELP!!! ... seriously?... This determines my grade in physics, and that's your answer? What I meant is that there is a 3d game on tv, I record it with a camera, then upload it.
