D3DXVEC3UNPROJECT functions
Put the vector from the screen space to the object space.
definition:
D3DXVECTOR3 * WINAPI D3DXVEC3UNPROJECT (D3DXVector3 * Pout,
Const D3DxVector3 * PV,
Const d3dviewport9 * PViewPort,
Const D3DXMAMATRIX * PPROJECTION,
Const d3dxmatrix * pVIEW,
Const d3dxmatrix * PWORLD
);
Parameters
pout
[IN, OUT] points to the operation result of the D3DXVECTOR3 structure.
PV
[in] Points to the vector of D3DXVector3.
PViewPort
[in] points to the viewport of the D3DViewPort9 structure.
PPROJECTION
[in] points to the projection matrix of the D3DXMatrix structure.
PVIEW
[in] Points to the D3DxMatrix structure of the viewing matrix.
PWORLD
[in] The world transformation matrix of D3DXMatrix structure.
return value:
Pointing the vector of the D3DxVector3 structure, which is the result of projecting vector from the screen space to the object space.
Description:
The function return value is the same as the POUT parameter. This allows functions D3DXVEC3UnProject to use parameters of other functions.
