Vector3D.Z 属性

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

获取或设置此 Vector3D 结构的 Z 组件。

public:
 property double Z { double get(); void set(double value); };

public double Z { get; set; }

member this.Z : double with get, set

Public Property Z As Double

属性值

Double

此 Vector3D 结构的 Z 组件。 默认值为 0。

示例

以下示例演示如何计算两 Vector3D 个结构的点积。 它还演示如何在声明结构时以及声明结构后向 Vector3D 结构赋值。

    // Calculates the Dot Product of two Vectors.

    // Declaring vector1 and initializing x,y,z values
    Vector3D vector1 = new Vector3D(20, 30, 40);

    // Declaring vector2 without initializing x,y,z values
    Vector3D vector2 = new Vector3D();

    // A Double to hold the result of the operation
    Double dotProduct;

    // Assigning values to vector2
    vector2.X = 45;
    vector2.Y = 70;
    vector2.Z = 80;

    // Calculating the dot product of vector1 and vector2
    dotProduct = Vector3D.DotProduct(vector1, vector2);

    // vectorResult is equal to (6200)

' Calculates the Dot Product of two Vectors.

' Declaring vector1 and initializing x,y,z values
Dim vector1 As New Vector3D(20, 30, 40)

' Declaring vector2 without initializing x,y,z values
Dim vector2 As New Vector3D()

' A Double to hold the result of the operation
Dim dotProduct As Double

' Assigning values to vector2
vector2.X = 45
vector2.Y = 70
vector2.Z = 80

' Calculating the dot product of vector1 and vector2
dotProduct = Vector3D.DotProduct(vector1, vector2)

' vectorResult is equal to (6200)
