D3DXVEC2TRANSFORMCOORDARRAY function
Transform a set of vector (x, y, 0, 1) with a matrix, and projected its result to W = 1.
definition:
D3DXVECTOR2 * WINAPI D3DXVEC2TRANSFORMCOORDARRAY
D3DXVECTOR2 * Pout,
Uint Outstride,
Const d3dxvector2 * pv,
Uint vstride,
Const d3dxmatrix * pm,
Uint N
);
parameter:
pout
[IN, OUT] points to the operation result of the D3DXVECTOR2 structure.
Outstride
[in] The size of the elements of the output vector array.
PV
The source vector array of D3DXVECTOR2 structures is directed.
Vstride
[in] The size of the elements of the vector array input.
pm
[in] points to the transformation matrix of the D3DXMatrix structure.
n
[IN] Enter the number of elements of the vector array.
return value:
Refers to the replacement array of D3DXVector4 structures.
Description:
This function is converted with a matrix PM transform array PV (X, Y, 0, 1), which sets the projection coordinates of the vector to be W = 1.
The function return value is the same as the POUT parameter. This allows the function D3DXVEC2TRANSFORMCOORDARRAY to use parameters of other functions.
