The DirectX7.IdentityMatrix method creates an identity matrix.
object.IdentityMatrix(mDest As D3DMATRIX)
If the method fails, an error is raised and Err.Number is set.
The identity matrix is a matrix in which 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 will modify vertex values to create rotations, translations, and any other transformations that can be represented by a 4×4 matrix.
