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

Compute silhouettes of a shape for a parallel projection.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
public static Silhouette[] Compute(
	GeometryBase geometry,
	SilhouetteType silhouetteType,
	Vector3d parallelCameraDirection,
	double tolerance,
	double angleToleranceRadians,
	IEnumerable<Plane> clippingPlanes,
	CancellationToken cancelToken
)

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.

Return Value

Type: Silhouette
Array of silhouette curves.
