vArrayRelaxOnMesh
Moves each point toward the average of its 6 nearest points, then snaps it to the closest mesh vertex.
vArrayRelaxOnMesh takes an array of XYZ points and a mesh, and repeats a smoothing pass Relax Iterations times. Relax Strength sets how far each point moves in a pass.
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
| Surface Offset | Float | 0 | Distance from the vertex along its estimated normal. Slider -1 to 1, default 0. |
| Relax Iterations | Integer | 10 | Number of passes. Minimum 1, slider 1 to 100, default 10. |
| Relax Strength | Float | 0.5 | How far a point moves toward the average of its neighbors in a pass. Range 0 to 1, default 0.5. |
| Affect X | Float | 1 | X comes from the result when checked (default), otherwise it keeps the input value. |
| Affect Y | Float | 1 | Y comes from the result when checked (default), otherwise it keeps the input value. |

Read the full description
In each pass every point finds its 6 nearest other points and moves toward their average by Relax Strength (0 to 1, default 0.5). The moved point is then replaced by the closest Mesh Points vertex, plus Surface Offset along the normal estimated there. Relax Iterations (default 10) is the number of passes.
This pulls points toward their neighbors and does not push them apart. After the last pass the points lie on mesh vertices, so points can share a vertex. Affect X, Y and Z keep unchecked axes at the input value. Only the vertex list of the mesh is used. If Points or Mesh Points is empty, the output is empty.
