D3DXVec3UnprojectArray function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Projects an array (x, y, z, 0) from screen space into object space.
Syntax
D3DXVECTOR3* D3DXVec3UnprojectArray(
_Inout_ D3DXVECTOR3 *pOut,
_In_ UINT OutStride,
_In_ const D3DXVECTOR3 *pV,
_In_ UINT VStride,
_In_ const D3DVIEWPORT9 *pViewport,
_In_ const D3DXMATRIX *pProjection,
_In_ const D3DXMATRIX *pView,
_In_ const D3DXMATRIX *pWorld,
_In_ UINT n
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR3*
Pointer to the D3DXVECTOR3 structure that is the result of the operation.
-
OutStride [in]
-
Type: UINT
Stride between vectors in the output data stream.
-
pV [in]
-
Type: const D3DXVECTOR3*
Pointer to the source D3DXVECTOR3 structure.
-
VStride [in]
-
Type: UINT
Stride between vectors in the input data stream.
-
pViewport [in]
-
Type: const D3DVIEWPORT9*
Pointer to a D3DVIEWPORT9 structure, representing the viewport.
-
pProjection [in]
-
Type: const D3DXMATRIX*
Pointer to a D3DXMATRIX structure, representing the projection matrix.
-
pView [in]
-
Type: const D3DXMATRIX*
Pointer to a D3DXMATRIX structure, representing the view matrix.
-
pWorld [in]
-
Type: const D3DXMATRIX*
Pointer to a D3DXMATRIX structure, representing the world matrix.
-
n [in]
-
Type: UINT
Number of elements in the array.
Return value
Type: D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure that is the array projected from screen space to object space.
Remarks
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3Unproject function can be used as a parameter for another function.
