--- UPDATE The sidefx labs "progressive resample" has adapted a very similar approach and can now be used to get these results as well ---
Two fun ways to resample curves non-uniformly:
Resample all incoming polylines by a set point count and a rampable density, or resample based on a painted density attribute. Great little tools for when you need precise control over point distribution.
Includes a minimal distance if you don't want points with density 1 to end up on top of each other and a toggle to close primitives.
