This has currently got me stumped and im hoping someone may know the formula for working this out, its quit hard to explain but ill try my best. Its to take data from a winch automation system where i am given the wire lengths and need to know where they join/intersect in 3d space to represent the actual object.

Picture this:

Four steel wires hanging from the corners of a roof of a room which is 4m x 4m.

Where the four wires come together an object is hanging off this point and by adjusting the lengths of each wire we can move the object hanging off them in 3D space within the confines of the “room x,y,z” which we theoretically know.

if we know that the base points for each wire is at each corner of a square which is 4m x 4m.

AND we know the length of each wire, does anyone know a way or a formula to interpolate these values to give the position of the apex in x,y,z values.

Im absolutely certain there is a way but i may be searching in the wrong direction, its quite an exciting challenge but i am currently stuck! Any suggestions pointers or tips would be much appreciated!

P.S, i apologise if i have completely missed a node which does this in 3d in vvvv, im only picking this up again after a while!
