Finds the intersection of two lines.

Syntax


XMVECTOR XMVector2IntersectLine(
  [in] XMVECTOR Line1Point1,
  [in] XMVECTOR Line1Point2,
  [in] XMVECTOR Line2Point1,
  [in] XMVECTOR Line2Point2
);

Parameters

Line1Point1 [in]: 2D vector describing the first point on the first line.
Line1Point2 [in]: 2D vector describing a second point on the first line.
Line2Point1 [in]: 2D vector describing the first point on the second line.
Line2Point2 [in]: 2D vector describing a second point on the second line.

Return value

Returns the intersection point. If the lines are parallel, the returned vector will be a NaN. If the two lines are coincident, the returned vector will be positive infinity.
