Finds the intersection of two planes.

Syntax

void XM_CALLCONV XMPlaneIntersectPlane(
  [out] XMVECTOR  *pLinePoint1,
  [out] XMVECTOR  *pLinePoint2,
  [in]  FXMVECTOR P1,
  [in]  FXMVECTOR P2
) noexcept;

Parameters

[out] pLinePoint1

Address of a 3D vector describing one point on the line of intersection. See remarks.

[out] pLinePoint2

Address of a 3D vector describing a second point on the line of intersection. See remarks.

[in] P1

XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation Ax+By+Cz+D=0.

[in] P2

XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation Ax+By+Cz+D=0.

Return value

None.

Remarks

If the planes are parallel to one another, all components of the returned point vectors are equal to QNaN.

Platform Requirements
