D3DXPlaneIntersectLine
Finds the intersection between a plane and a line.
D3DXVECTOR3 * D3DXPlaneIntersectLine(
D3DXVECTOR3 * pOut,
CONST D3DXPLANE * pP,
CONST D3DXVECTOR3 * pV1,
CONST D3DXVECTOR3 * pV2
);
Parameters
pOut
[in, out] Pointer to a D3DXVECTOR3 structure, identifying the intersection between the specified plane and line.
pP
[in] Pointer to the source D3DXPLANE structure.
pV1
[in] Pointer to a source D3DXVECTOR3 structure, defining a line starting point.
pV2
[in] Pointer to a source D3DXVECTOR3 structure, defining a line ending point.
Return Values
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.
