ID3DXMATRIXStack::LoadIdentity method (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead along with this header from GitHub.
Loads identity in the current matrix.
Syntax
HRESULT LoadIdentity();
Parameters
This method has no parameters.
Return value
Type: HRESULT
If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be D3DERR_INVALIDCALL.
Remarks
The identity matrix is a matrix in which all coefficients are 0.0 except the [1,1][2,2][3,3][4,4] coefficients, which are set to 1.0. 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 4x4 matrix.
