XMPlaneIntersectPlane method

Finds the intersection of two planes.

Syntax


VOID XMPlaneIntersectPlane(
  [out]  XMVECTOR *pLinePoint1,
  [out]  XMVECTOR *pLinePoint2,
  [in]   XMVECTOR P1,
  [in]   XMVECTOR P2
);

Parameters

pLinePoint1 [out]

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

pLinePoint2 [out]

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

P1 [in]

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

P2 [in]

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
