BrepEdgeGet3dVectorsIntoFaces Method

For each trim at this edge, find the 3d unit vector at the edge parameter in the trim's surface tangent plane, perpendicular to the edge, which points to the active side of the trim.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Since: 9.0

Syntax

Copy

public bool Get3dVectorsIntoFaces(
	double t,
	out Vector3d[] vectors,
	out Vector3d[] normals
)

Public Function Get3dVectorsIntoFaces ( 
	t As Double,
	<OutAttribute> ByRef vectors As Vector3d(),
	<OutAttribute> ByRef normals As Vector3d()
) As Boolean

Parameters

t: Type: SystemDouble
edge parameter where vectors and normals are evaluated
vectors: Type: Rhino.GeometryVector3d
3d vectors point into the face(s). One for each trim, in order of TrimIndices
normals: Type: Rhino.GeometryVector3d
Surface normals at edge parameter. Perpendicular to the 3d vectors.

Return Value

Type: Boolean
True if vectors can be found. False if edge tangent or surface normals can't be found, or if input is bad.
