Intersection.RayShoot Method (Ray3d, IEnumerable(GeometryBase), Int32)

IntersectionRayShoot Method (Ray3d, IEnumerableGeometryBase, Int32)

Computes point intersections that occur when shooting a ray to a collection of surfaces and Breps.

Namespace:  Rhino.Geometry.Intersect
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
Syntax
Copy
public static Point3d[] RayShoot(
	Ray3d ray,
	IEnumerable<GeometryBase> geometry,
	int maxReflections
)
Public Shared Function RayShoot ( 
	ray As Ray3d,
	geometry As IEnumerable(Of GeometryBase),
	maxReflections As Integer
) As Point3d()

Parameters

ray
Type: Rhino.GeometryRay3d
A ray used in intersection.
geometry
Type: System.Collections.GenericIEnumerableGeometryBase
Only Surface and Brep objects are currently supported. Trims are ignored on Breps.
maxReflections
Type: SystemInt32
The maximum number of reflections. This value should be any value between 1 and 1000, inclusive.

Return Value

Type: Point3d
An array of points: one for each surface or Brep face that was hit, or an empty array on failure.
Exceptions
ExceptionCondition
ArgumentNullExceptiongeometry is null.
ArgumentOutOfRangeExceptionmaxReflections is strictly outside the [1-1000] range.
