Definition

Visual Basic Public Shared  ReadOnly Property Identity As Matrix

Microsoft.DirectX.Matrix
A Matrix structure that represents the matrix identity.

This property is read-only. 

Remarks

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 is special in that 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 4x4 matrix.
