Class MeshInsertUVPolyCurve

Cut mesh with a path of 2D line segments Assumptions:

  • mesh vertex x/y coordinates are 2D coordinates we want to use. Replace PointF if this is not the case.
  • segments of Curve lie entirely within UV-triangles

Limitations:

  • currently not robust to near-parallel line segments that are within epsilon-band of the input loop. In this case, we will include all such segments in the 'cut' set, but we will probably not be able to find a connected path through them.
  • not robust to degenerate geometry. Strongly recommend that you use Validate() and/or preprocess the input mesh to remove degenerate faces/edges

Methods

Apply()

Declaration
public virtual bool Apply()
Returns
Type Description
Boolean

Simplify()

Generally after calling Apply(), we have over-triangulated the mesh, because we have split the original edges multiple times, etc. This function will walk the edges and collapse the unnecessary edges/vertices along the inserted loops.

Declaration
public void Simplify()

Validate(Double)

public virtual ValidationStatus Validate(double fDegenerateTol = 9.9999999747524271E-07)
Parameters
Type Name Description
Double fDegenerateTol
Returns
Type Description
ValidationStatus
