Syntax

public void RayTest(
        Point3d rayBasePoint,
        Vector3d rayDir,
        double rayRadius,
        out SubentityId[] subEntIds,
        out DoubleCollection parameters
)

Public Sub RayTest ( 
        rayBasePoint As Point3d,
        rayDir As Vector3d,
        rayRadius As Double,
        <OutAttribute> ByRef subEntIds As SubentityId(),
        <OutAttribute> ByRef parameters As DoubleCollection
)

public:
void RayTest(
        Point3d rayBasePoint, 
        Vector3d rayDir, 
        double rayRadius, 
        [OutAttribute] array<SubentityId>^% subEntIds, 
        [OutAttribute] DoubleCollection^% parameters
)

member RayTest : 
        rayBasePoint : Point3d * 
        rayDir : Vector3d * 
        rayRadius : float * 
        subEntIds : SubentityId[] byref * 
        parameters : DoubleCollection byref -> unit

Parameters

rayBasePoint Point3d: [in] Base point to start a ray from.
rayDir Vector3d: [in] Ray direction.
rayRadius Double: [in] Ray radius, which defines the tolerance used for intersection checking.
subEntIds SubentityId: [out] Receives an array of subentities. It can contain one of the following: faces, edges or vertices.
parameters DoubleCollection: [out] Receives an array of parameters. Parameters show the intersection between a ray and subentities.

Remarks

This method is implemented only for the Spatial modeler.
