VB

Public Shared Function MeshRay ( 
	mesh As Mesh,
	ray As Ray3d,
	<OutAttribute> ByRef meshFaceIndices As Integer()
) As Double

mesh

Type: Rhino.Geometry.Mesh
A mesh to intersect.

ray

Type: Rhino.Geometry.Ray3d
A ray to be casted.

meshFaceIndices

Type: System.Int32[]
faces on mesh that ray intersects.

Type: Double
>= 0.0 parameter along ray if successful. < 0.0 if no intersection found.

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.
