Changes this Matrix3D structure into an identity matrix.

member this.SetIdentity : unit -> unit
Public Sub SetIdentity ()

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.
