Finds the intersection between a plane and a line.

Syntax

XMVECTOR XM_CALLCONV XMPlaneIntersectLine(
  [in] FXMVECTOR P,
  [in] FXMVECTOR LinePoint1,
  [in] FXMVECTOR LinePoint2
) noexcept;

Parameters

[in] P

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

[in] LinePoint1

3D vector describing the first point on the line.

[in] LinePoint2

3D vector describing the second point on the line.

Return value

Returns the intersection of the plane P and the line defined by LinePoint1 and LinePoint2. If the line is parallel to the plane, all components of the returned vector are equal to QNaN.

Remarks

Platform Requirements
