Intersection.MeshRay Method (Mesh, Ray3d, Int32[])

IntersectionMeshRay Method (Mesh, Ray3d, Int32)

Finds the first intersection of a ray with a mesh.

Namespace:  Rhino.Geometry.Intersect
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
Copy
public static double MeshRay(
	Mesh mesh,
	Ray3d ray,
	out int[] meshFaceIndices
)
Public Shared Function MeshRay ( 
	mesh As Mesh,
	ray As Ray3d,
	<OutAttribute> ByRef meshFaceIndices As Integer()
) As Double

Parameters

mesh
Type: Rhino.GeometryMesh
A mesh to intersect.
ray
Type: Rhino.GeometryRay3d
A ray to be casted.
meshFaceIndices
Type: SystemInt32
faces on mesh that ray intersects.

Return Value

Type: Double
>= 0.0 parameter along ray if successful. < 0.0 if no intersection found.
Remarks
The ray may intersect more than one face in cases where the ray hits the edge between two faces or the vertex corner shared by multiple faces.
