Follow up from: https://stackoverflow.com/questions/5225061/exponential-decay-surrounding-bounding-box
How can I manipulate a simple logistic function like this one:
So that the lower bound is at 0, and the (-3, 3) range is roughly doubled and depends on some value (the lower edge of the bounding box as described in the original question)
And then how would I flip the function horizontally, so that it can work for the upper edge of the box?
Maths n00b, sorry
