Namespace: Rhino.Geometry.Intersect

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**5.0

Syntax

public static double MeshRay(
  Mesh mesh,
  Ray3d ray,
  out int[] meshFaceIndices
)

Parameters

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.

Return Value

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