Houdini 20.0 Nodes Geometry nodes

Labs Curve Resample by Density 1.0 geometry node

Redistributes curve points based on density.

This node resamples and adjusts the positions of points on curves based on a density ramp, a weight attribute, or curvature. It can operate on multiple curves at once using the same settings.

Note

This node replaces Labs Progressive Resample SOP, which will be removed in Houdini 20.5.

Parameters

Maximum Segments

Specify the maximum number of edges for each curve.

Segments

The maximum number of edges for each curve.

Resample

Resample by

There are three different ways to resample the curves. Resample by Ramp, by an Attribute, or by Curvature.

Ramp

Density along Curve

Controls the density of the redistributed points along each curve. The X axis of the ramp represents the full length of each curve. (The direction is the increasing direction of the curve’s parametric u coordinate.) The Y axis represents the concentration of points. Higher values mean denser distribution of points.

Density Ramp Samples

You generally do not need to change this. The area under the density ramp is integrated over this many discrete slices. The more slices there are, the more accurately the ramp is intepreted. Only consider increasing this value if your ramp has many ups and downs.

Weight Attribute

Weight Attribute

Controls the density of the redistributed points along each curve based on a weight attribute.

Curvature

Controls the density of the redistributed points along each curve based on the curvature of each curve.
