IntersectionMeshMeshPredicate Method (IEnumerableMesh, IEnumerableMesh, Double, Boolean, TextLog, CancellationToken)

Determines whether any of the meshes intersect. No geometry is computed, and the search stops at the first pair of meshes that intersect: this is the quickest answer when the intersecting pairs are not needed.

Namespace:  Rhino.Geometry.Intersect
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 9.0
Syntax
Copy
public static bool MeshMeshPredicate(
	IEnumerable<Mesh> meshesA,
	IEnumerable<Mesh> meshesB,
	double tolerance,
	bool fast,
	TextLog textLog,
	CancellationToken cancel
)

Parameters

meshesA
Type: System.Collections.GenericIEnumerableMesh
The first mesh list. This cannot be null. Null entries are skipped.
meshesB
Type: System.Collections.GenericIEnumerableMesh
A second mesh list, or null. When null, every pair within meshesA is tested once; otherwise every mesh of meshesA is tested against every mesh of meshesB. Null entries are skipped.
tolerance
Type: SystemDouble
A tolerance value. If negative, the positive value will be used. WARNING! Good tolerance values are in the magnitude of 10^-7, or RhinoMath.SqrtEpsilon*10.
fast
Type: SystemBoolean
True uses the fast intersector behind MeshMeshFast(Mesh, Mesh): faces that cross or touch within tolerance count, coplanar overlap without a crossing does not. False uses the accurate intersector, which also reports coplanar overlap and costs about as much as MeshMeshFast(Mesh, Mesh).
textLog
Type: Rhino.FileIOTextLog
A text log, or null.
cancel
Type: System.ThreadingCancellationToken
A cancellation token to stop the computation at a given point.

Return Value

Type: Boolean
True if any pair intersects, otherwise false. False is also returned on error or cancellation.
