Matrix3D.Identity Property

Changes a Matrix3D structure into an identity Matrix3D.

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

public static Matrix3D Identity { get; }

Property Value

Type: System.Windows.Media.Media3D.Matrix3D
The identity Matrix3D.

In an identity matrix, all coefficients are 0 except the [1,1][2,2][3,3][4,4] coefficients, which are set to 1. The identity matrix differs from other matrices because when it is applied to vertices, they are unchanged.

The identity matrix is used as the starting point for matrices that modify vertex values to create rotations, translations, and any other transformations that can be represented by a 4 × 4 matrix.
