Vector3D.DotProduct Method

Calculates the dot product of two Vector3D structures.

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

public static double DotProduct(
	Vector3D vector1,
	Vector3D vector2
)

Parameters

vector1
Type: System.Windows.Media.Media3D.Vector3D

The first Vector3D structure to evaluate.

vector2
Type: System.Windows.Media.Media3D.Vector3D

The second Vector3D structure to evaluate.

Return Value

Type: System.Double
The dot product of vector1 and vector2.

The following example shows how to calculate the dot product of two Vector3D structures.

// 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)
