3d delta printer - help

Hello, I was looking a little about this printer,
a little different to the other using a coordinate system moving.

this not understand how to find the conponentes (x, y, z) for the motors,

For example, given a position of the print head (10,20,50) as meeting
the conponente of each motor.?

This is an interesting concept that I've never seen before. Is it actually in use? Are the arm lengths also adjustable?

Wow that's heavy going! It looks like a lot of work.
