Vector4.Cross(Vector4, Vector4) Method
Definition

Computes the cross product of two vectors. For homogeneous coordinates, the product of the weights is the new weight for the resulting product.

static System::Numerics::Vector4 Cross(System::Numerics::Vector4 vector1, System::Numerics::Vector4 vector2);public static System.Numerics.Vector4 Cross(System.Numerics.Vector4 vector1, System.Numerics.Vector4 vector2);static member Cross : System.Numerics.Vector4 * System.Numerics.Vector4 -> System.Numerics.Vector4Public Shared Function Cross (vector1 As Vector4, vector2 As Vector4) As Vector4Parameters
- vector1
- Vector4
The first vector.
- vector2
- Vector4
The second vector.
Returns
The cross product.
Remarks
The proposed Cross function for Vector4 is nearly the same as that for Cross(Vector3, Vector3) with the addition of the fourth value which is the product of the original two w's. This can be derived by symbolically performing the cross product for Vector3 with values [x_1/w_1, y_1/w_1, z_1/w_1] and [x_2/w_2, y_2/w_2, z_2/w_2].
