We hope that the resample node can output the added points and the previous points, respectively.
Sometimes we do something about the previous point, such as n constraints. When we use resample processing, hoping to distinguish between the previous point and increase the point. This will preserve the processing of previous points. For example, keep the same point constraints.
There is another suggestion that is not very important. Resample can enter the curve, it will be more perfect. Now, you can use the node of soup to let it process the curve. But if you can handle the curve directly, that would be better.
