I have a trouble understanding what the node Curve.ParameterAtPoint values are? For example, in the below pic there is curve split by nodes and points defined at parameter which is starting, mid, end point parameter. We input those points as a parameter into Curve.ParameterAtPoint node and it returns some values relating to the curve. Can you explain me what do those values represent? How, in the first place, ParameterAtPoint node obtains those valuse? Let’s say if the points were not on the curve what will it give as a parameter and how it obtained that values?
