Vector3D.X Property

Gets or sets the X component of this Vector3D structure.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

public double X { get; set; }
<object X="double" .../>

Property Value

Type: System.Double
The X component of this Vector3D structure. The default value is 0.

The following example shows how to calculate the dot product of two Vector3D structures. It also shows how to assign values to a Vector3D structure when the structure is being declared and after the structure has been declared.

// 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)
