Примеры

В следующем примере показано, как вычислить точечный продукт двух Vector3D структур.

    // 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
