Intersection.RayShoot Method

RhinoCommon API

IntersectionRayShoot Method

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

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

Syntax

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 face that was passed by the faceIds out reference.

Exceptions

Exception	Condition
ArgumentNullException	geometry is null.
ArgumentOutOfRangeException	maxReflections is strictly outside the [1-1000] range.
