IntersectionMeshRays Method (Mesh, IEnumerableRay3d)

Finds the first intersection of each one of a set of rays with a mesh.

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

Since: 9.0

Syntax

public static double[] MeshRays(
	Mesh mesh,
	IEnumerable<Ray3d> rays
)

Public Shared Function MeshRays ( 
	mesh As Mesh,
	rays As IEnumerable(Of Ray3d)
) As Double()

Parameters

mesh: Type: Rhino.GeometryMesh
A mesh to intersect.
rays: Type: System.Collections.GenericIEnumerableRay3d
The rays to cast.

Return Value

Type: Double
One value for each ray, in the order of the rays: the parameter along that ray of its first intersection with the mesh, or a value smaller than 0.0 where that ray does not meet the mesh. Null when the mesh or the set of rays is null.

Remarks

The rays are cast on several threads, so this is much faster than one call of MeshRay(Mesh, Ray3d) per ray.
