Viewport3D.Camera 属性

定义

命名空间:

System.Windows.Controls

程序集:

PresentationFramework.dll

获取或设置一个相机对象，该对象投影到 Viewport3D 二维图面 Viewport3D的三维内容。

public:
 property System::Windows::Media::Media3D::Camera ^ Camera { System::Windows::Media::Media3D::Camera ^ get(); void set(System::Windows::Media::Media3D::Camera ^ value); };

public System.Windows.Media.Media3D.Camera Camera { get; set; }

member this.Camera : System.Windows.Media.Media3D.Camera with get, set

Public Property Camera As Camera

属性值

Camera

将三维内容投影到二维图面的相机。

示例

以下示例演示如何设置 Camera using 代码的属性 Viewport3D 。 若要查看从中提取此摘录的完整代码，请参阅 “如何：创建三维场景”。

// Defines the camera used to view the 3D object. In order to view the 3D object,
// the camera must be positioned and pointed such that the object is within view 
// of the camera.
PerspectiveCamera myPCamera = new PerspectiveCamera();

// Specify where in the 3D scene the camera is.
myPCamera.Position = new Point3D(0, 0, 2);

// Specify the direction that the camera is pointing.
myPCamera.LookDirection = new Vector3D(0, 0, -1);

// Define camera's horizontal field of view in degrees.
myPCamera.FieldOfView = 60;

// Asign the camera to the viewport
myViewport3D.Camera = myPCamera;

' Defines the camera used to view the 3D object. In order to view the 3D object,
' the camera must be positioned and pointed such that the object is within view 
' of the camera.
Dim myPCamera As New PerspectiveCamera()

' Specify where in the 3D scene the camera is.
myPCamera.Position = New Point3D(0, 0, 2)

' Specify the direction that the camera is pointing.
myPCamera.LookDirection = New Vector3D(0, 0, -1)

' Define camera's horizontal field of view in degrees.
myPCamera.FieldOfView = 60

' Asign the camera to the viewport
myViewport3D.Camera = myPCamera

以下示例演示如何设置 Camera 使用可扩展应用程序标记语言的属性 Viewport3D (XAML) 。 若要查看从中提取此摘录的完整代码，请参阅 “如何：创建三维场景”。

<!-- Add a camera. -->
<Viewport3D.Camera>
    <PerspectiveCamera FarPlaneDistance="20" LookDirection="5,-2,-3" UpDirection="0,1,0" NearPlaneDistance="1" Position="-5,2,3" FieldOfView="45" />
</Viewport3D.Camera>
