Mesh.CollapseFacesByEdgeLength

Public Class

Collapses multiple mesh faces, with greater/less than edge length, based on the principles found in Stan Melax’s mesh reduction PDF, see http://pomax.nihongoresources.com/downloads/PolygonReduction.pdf

Namespace: Rhino.Geometry

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**6.0

Syntax

public int CollapseFacesByEdgeLength(
  bool bGreaterThan,
  double edgeLength
)

Parameters

bGreaterThan

Type:System.Boolean
Determines whether edge with lengths greater than or less than edgeLength are collapsed.

edgeLength

Type:System.Double
Length with which to compare to edge lengths.

Return Value

Type:Int32
Number of edges (faces) that were collapsed, -1 for general failure (like bad topology or index out of range) or -2 if all of the edges would be collapsed and the resulting mesh would be invalid.

Remarks

This number may differ from the initial number of edges that meet the input criteria because the lengths of some initial edges may be altered as other edges are collapsed.
