D3DXVEC2TRANSFORMCOORD function
Transform a 2-D vector with a matrix, but the projecting item W = 1.
definition:
D3DXVECTOR2 * WINAPI D3DXVEC2TRANSFORMCOORD (
D3DXVECTOR2 * Pout,
Const d3dxvector2 * pv,
Const D3DXMatrix * PM
);
parameter:
pout
[IN, OUT] points to the operation result of the D3DXVECTOR2 structure.
PV
[in] Point the source vector of the D3DxVector2 structure.
pm
[in] points to the source matrix of the D3DXMatrix structure.
return value:
Refers to the changed vector of the D3DXVector2 structure.
Description:
This function is converted with a matrix, then returns the result vector PV (x, y, 0, 1), the projection value W = 1.
The function return value is the same as the POUT parameter. This allows functions D3DXVEC2TRANSFORMCOORD as a parameter of other functions.
