Hi guys, Here is what I'm doing: A B C D I want the distance from a point to have less influence. So let's say from A to B (and also A to C) is 1.0, then A to D is 1.41 but I want it so the farther away it is the lower the number, so should I use 1.0 / 1.41 = 0.71 ? Does that seem right ? Thanks.

That would be the easyest way but there are many more ways to do that. What are you tring to do exactly?

The power of most physical phenomenon (in the real world) falls off at a rate of 1 / distance^2. Which makes sense, if you think about it. If you have a point with a sphere of influence, the influence will decline at a rate proportional to the distance squared.
