SilhouetteCompute Method (GeometryBase, SilhouetteType, Vector3d, Double, Double, IEnumerablePlane, CancellationToken)

public static Silhouette[] Compute(
	GeometryBase geometry,
	SilhouetteType silhouetteType,
	Vector3d parallelCameraDirection,
	double tolerance,
	double angleToleranceRadians,
	IEnumerable<Plane> clippingPlanes,
	CancellationToken cancelToken
)

Public Shared Function Compute ( 
	geometry As GeometryBase,
	silhouetteType As SilhouetteType,
	parallelCameraDirection As Vector3d,
	tolerance As Double,
	angleToleranceRadians As Double,
	clippingPlanes As IEnumerable(Of Plane),
	cancelToken As CancellationToken
) As Silhouette()

Parameters

geometry

Type: Rhino.GeometryGeometryBase
Geometry whose silhouettes need to be computed. Can be Brep, BrepFace, Mesh, or Extrusion.

silhouetteType

Type: Rhino.GeometrySilhouetteType
Types of silhouette to compute.

parallelCameraDirection

Type: Rhino.GeometryVector3d
Direction of parallel camera.

tolerance

Type: SystemDouble
Tolerance to use for determining projecting relationships. Surfaces and curves that are closer than tolerance, may be treated as projecting. When in doubt use RhinoDoc.ModelAbsoluteTolerance.

angleToleranceRadians

Type: SystemDouble
Angular tolerance to use for determining projecting relationships. A surface normal N that satisfies N o cameraDirection < Sin(angleToleranceRadians) may be considered projecting. When in doubt use RhinoDoc.ModelAngleToleranceRadians.

clippingPlanes

Type: System.Collections.GenericIEnumerablePlane
Optional collection of clipping planes.

cancelToken

Type: System.ThreadingCancellationToken
Computation cancellation token.
