[Numpy-discussion] Distance Formula on an Array

[Ian Mallett]

The problem is that the object moves too much between frames.  A reasonable
bounding sphere is 1 for this purpose, but the objects move at least 3.  So,
given the two arrays, one holding the objects' positions and the other their
previous positions, how can I find if, at some point between, the objects
collided with the bounding sphere?
