Thought o’ the Day: Motion is Relative, Especially in Games

Motion is relative. Say you’re an object… some abstract object. You move about; how do you know? Well, you say to your self, “Self, I see that other object changing it’s location on my visual field. Either I’m moving, or it’s moving, or we’re both moving.” So unless you have another object to give you reference for motion, you can’t really say if you’re moving or not.

If you don’t believe it, then you’ve never debugged a camera that’s rendering a blank scene or one that’s lost track of the game scene that you should be following. Bugger it all…
