Bend line between two points

1

Hi,

I am looking for an answer concerning the following problem: I want to draw a bent line between two points. Simply using bezier curves won’t do it though, as I want a fairly realistic behaviour and the two points are not necessarily on the same height.

Any ideas would be appreciated.

A curve between two points is a straight line. You need at least 3 points to create a curve, unless you plan on randomly choosing a third.

true. which is why I need some information on how to find the third point given the known distance and angle between the two points and the length of the “string” to connect them.

But a bezier curve is the very definition of your problem.

Anyway. I’m not sure I understand what information you want. How to find the third point? I mean that all depends on where you want to place it on the line? You have to realize that if you have two given points on random positions and a line in between you can place a third point pretty much wherever and then draw a curved line through it. Specifics please :slight_smile:

Firstly, thanks for the reply. Well, consider a physically realistic environment in which two points are connected by a string. The position of the third point would be dependent on the length of the string, the position of the two points, the gravity and mass, I think. Now I am looking for a function for that.
