D3DXPlaneIntersectLine function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Finds the intersection between a plane and a line.
Syntax
D3DXVECTOR3* D3DXPlaneIntersectLine(
_Inout_ D3DXVECTOR3 *pOut,
_In_ const D3DXPLANE *pP,
_In_ const D3DXVECTOR3 *pV1,
_In_ const D3DXVECTOR3 *pV2
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure, identifying the intersection between the specified plane and line.
-
pP [in]
-
Type: const D3DXPLANE*
Pointer to the source D3DXPLANE structure.
-
pV1 [in]
-
Type: const D3DXVECTOR3*
Pointer to a source D3DXVECTOR3 structure, defining a line starting point.
-
pV2 [in]
-
Type: const D3DXVECTOR3*
Pointer to a source D3DXVECTOR3 structure, defining a line ending point.
Return value
Type: D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure that is the intersection between the specified plane and line.
Remarks
If the line is parallel to the plane, NULL is returned.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXPlaneIntersectLine function can be used as a parameter for another function.
