Blender Geo nodes offset curve

Question

So I am in the process of writing a geo node modifier where I can create curves that are offset from the original curve by a certain amount.

I would like to be able to offset the curves by an amount that changes along the curve (see image bellow) but I am not certain how to do that.

here are the main nodes

here are the nodes that calculates the offset:

here is the current result:

and here is the desired outcome, where green is the main curve and red are the created curves:

Answer 1

You can use the curve factor to get a range between 0 and 1 along the curve.

That way, you can control the offset strength along the curve. Use a map range node if you want to have more control over the offset settings

Also, you should use a duplicate elements node instead of making a group for each curves, its better for performances and compatibility
