RayHitTestParameters.Origin 속성

정의

네임스페이스:

System.Windows.Media.Media3D

어셈블리:

PresentationCore.dll

적중 테스트를 수행할 광선의 원점을 가져옵니다.

public:
 property System::Windows::Media::Media3D::Point3D Origin { System::Windows::Media::Media3D::Point3D get(); };

public System.Windows.Media.Media3D.Point3D Origin { get; }

member this.Origin : System.Windows.Media.Media3D.Point3D

Public ReadOnly Property Origin As Point3D

속성 값

Point3D

적중 테스트를 수행할 광선의 원점입니다.

예제

public void HitTest(object sender, System.Windows.Input.MouseButtonEventArgs args)
{
    Point mouseposition = args.GetPosition(myViewport);
    Point3D testpoint3D = new Point3D(mouseposition.X, mouseposition.Y, 0);
    Vector3D testdirection = new Vector3D(mouseposition.X, mouseposition.Y, 10);
    PointHitTestParameters pointparams = new PointHitTestParameters(mouseposition);
    RayHitTestParameters rayparams = new RayHitTestParameters(testpoint3D, testdirection);

    //test for a result in the Viewport3D
    VisualTreeHelper.HitTest(myViewport, null, HTResult, pointparams);

Public Sub HitTest(ByVal sender As Object, ByVal args As MouseButtonEventArgs)
    Dim mouseposition As Point = args.GetPosition(myViewport)
    Dim testpoint3D As New Point3D(mouseposition.X, mouseposition.Y, 0)
    Dim testdirection As New Vector3D(mouseposition.X, mouseposition.Y, 10)
    Dim pointparams As New PointHitTestParameters(mouseposition)
    Dim rayparams As New RayHitTestParameters(testpoint3D, testdirection)

    'test for a result in the Viewport3D
    VisualTreeHelper.HitTest(myViewport, Nothing, AddressOf HTResult, pointparams)

설명

시각적 계층에서 점 또는 최상위 개체 뿐만 아니라 기 하 도형 아래의 모든 개체에 대해 적중 테스트 지원 하는지 참고 합니다. 또한 적중된 테스트를 2D 바로 아래에 지정 된 지점 또는 기 하 도형 3D 결과 반환 합니다.
