Add control point along spline
This can be used to add a new control point to a spline. This function is closely related to the Add Point to Spline Node. The desired position will, however, be set as a percentage in relation to the spline length.
In this example, a point is added to a rectangular spline.
The newly added point can be seen at the center of the top edge. For visualization purposes, spheres with the spline control point distribution were placed on the spline points.
