I am attempting to work out a time when two moving objects will collide. My simple example takes two simple circles, moving about a 2d world, with the movement of each circle being either linear, or something slightly more than simply linear.
I need to figure out when (if ever) these two circles "touch", without having to iteratively go through thousands of times checking each. I suppose what I would hope to get at the end of the calculation would be
-no solutions (they never could touch given their current paths).
-they only touch once
-they touch many times (of course with paths that may be circular themselves or similar).
I really would appreciate any insight into this problem.
