C#

public static Silhouette[] Compute(
	GeometryBase geometry,
	SilhouetteType silhouetteType,
	Vector3d parallelCameraDirection,
	double tolerance,
	double angleToleranceRadians
)

VB

Public Shared Function Compute ( 
	geometry As GeometryBase,
	silhouetteType As SilhouetteType,
	parallelCameraDirection As Vector3d,
	tolerance As Double,
	angleToleranceRadians As Double
) As Silhouette()

geometry

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

silhouetteType

Type: Rhino.Geometry.SilhouetteType
Types of silhouette to compute.

parallelCameraDirection

Type: Rhino.Geometry.Vector3d
Direction of parallel camera.

tolerance

Type: System.Double
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: System.Double
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.

Type: Silhouette[]
Array of silhouette curves.
