The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Creates an instance of the object that specifies the origin and direction of the ray along which to hit test.

Namespace:   System.Windows.Media.Media3D

public RayHitTestParameters(
	Point3D origin,
	Vector3D direction


Type: System.Windows.Media.Media3D.Point3D

Point3D at which the ray originates.

Type: System.Windows.Media.Media3D.Vector3D
