D3DXMAMATRIXIDENTITY function
Create a unit matrix.
definition:
D3DXMAMATRIX * D3DXMATRIXIDENTITITY
D3DXMAMATRIX * Pout
);
parameter:
pout
[IN, OUT] points to the return unit matrix of the D3DXMatrix structure.
return value:
Point the unit matrix of the D3DXMatrix structure.
Description:
The unit matrix is in addition to [1,1] [2, 2] [3, 3] [4, 4] diagonal coefficients, all of the other coefficients are 0. When multiplied by any other vertex vector, it is convenient to modify the unit matrix as a rotation, translation, and zoom matrix.
The return value is the same as the POUT parameter returns, so that this function can be the parameters of other functions.
