If you can think of what the term may be so that I can google for this myself that would be perfect. Lets say I have a collection (array) of x,y points, doesn't really matter what they are, heres the most basic example:
Heres my question. say I plot a line from 5,5 to -5,-5: I would like to know which other points are within a distance of x. If x = 3, 0,1 would be returned but 10,10 is obviously not within a distance of 3.
Again sorry for this, I dont need someone to teach me, just looking for the term so that I can do that on my own
Also, would the term be the same for a 3d plane? x,y and z?
For those interested, I think this source may be able to help me out:
I think you want the distance between a point and a line segment. Here's another possibly helpful link... http://geomalgorithms.com/a02-_lines.html
Ah thank you. I've got an idea on how to force this operation on both a 2d and 3d plane, but I wonder if theres a smooth way of doing this in a programming language. I am messing with this (slowly) and will put my results here as I come up with results.
EDIT: Scrolling down I actually see your page provides code examples, aswesome!
