Gets or sets a Boolean that specifies if WPF hit testing can be done on the instanced 3D objects when rendered with DirectX hardware acceleration. When IsWpfHitTestVisible is true then InstancedGeometryVisual3D always creates WPF's Model3D objects that are used by WPF's hit testing. This can increase initialization time. Default value is false.

public bool IsWpfHitTestVisible { get; set; }
