This is an Off Topic informal poll of sorts, but related to LiveCode as
I am writing a LiveCode expression to determine if 2 arbitrary
rectangles (r1,r2) are with some distance d (in px) of one another. In
considering this problem, the questions comes up: What is meant by
rectangles being within a distance d of one another. What is the 'd'
measured from?
center to center? Easiest is many ways, but I don't think this is what
most people would think of.
adjacent edge to adjacent edge? This is harder (I think), but I think
this is what more people intuitively think of. To me, implicit in the
visual concept of 2 rects being within some distance of one another is
that they are NOT overlapping, but that some gap exists between the
nearest adjacent edges?
Something else? What does 2 rects being 'within' d pixels of one
another mean to you, if not one of the two above options?
Maybe there is a exact mathematical definition of what 2 rectangles
being within distance d of one another is, but, if there is, I am
unfamiliar with it.
