PIXI.lineIntersection

lineIntersection(aStart: IPointData, aEnd: IPointData, bStart: IPointData, bEnd: IPointData, outPoint: IPointData) → {IPointData}

Computes the point where non-coincident and non-parallel Lines intersect. Coincident or parallel lines return a NaN point {x: NaN, y: NaN}. The intersection point may land outside the extents of the lines.

Note: Only available with @pixi/math-extras.

Parameters:
Name	Type	Description
aStart	IPointData	First point of the first line.
aEnd	IPointData	Second point of the first line.
bStart	IPointData	First point of the second line.
bEnd	IPointData	Second point of the second line.
outPoint	IPointData	A Point-like object in which to store the value, optional (otherwise will create a new Point).

Returns:
Type	Description
IPointData	The point where the lines intersect or a `NaN` Point.
