D3DXMatrixmultiply function
Two matrices are multiplied.
definition:
D3DXMAMATRIX * WINAPI D3DXMATRIXMULTIPLY
D3DXMAMATRIX * POUT,
Const d3dxmatrix * PM1,
Const D3DXMatrix * PM2
);
parameter:
pout
[IN, OUT] points to the matrix product of the D3DXMatrix structure.
PM1
[in] points to the source matrix of the D3DXMatrix structure.
PM2
[in] points to the source matrix of the D3DXMatrix structure.
return value:
Points to multiplied by two matrices of the D3DXMatrix structure.
Description:
This function mainly allows two matrices to multiply, and the expression is the matrix 1 transformation, then the matrix 2 transform is then Such as formula (OUT = M1 * M2), in fact, in C , it can be used to operate there in the formula without this function.
The return value is the same as the parameter POUT value. This method allows D3DXMatrixMultiply as a parameter of other functions.
