lineSegmentXYUVOverlapUnbounded MethodStatic
Intersect two overlapping unbounded 2D lines.
lineSegmentXYUVOverlapUnbounded(a0: Readonly<WritableXAndY>, aDir: Readonly<WritableXAndY>, b0: Readonly<WritableXAndY>, bDir: Readonly<WritableXAndY>, tol: numberGeometry.smallMetricDistance): undefined | { f0: WritableXAndY, f1: WritableXAndY }
@returns undefined if the lines have a simple (transverse) intersection, or are parallel without overlap.
Otherwise, return the fractions at which each segment overlaps the other line:
- segment B maps to fractions in the range f0.x < f1.x on line A.
- segment A maps to fractions in the range f0.y < f1.y on line B.

| Parameter | Type | Description |
|---|---|---|
| a0 | Readonly<WritableXAndY> | start point of line A |
| aDir | Readonly<WritableXAndY> | direction vector of line A; end point of line segment A is a0 + aDir |
| b0 | Readonly<WritableXAndY> | start point of line B |
| bDir | Readonly<WritableXAndY> | direction vector of line B; end point of line segment B is b0 + bDir |
| tol | number | overlap distance tolerance |
Returns - undefined | { f0: WritableXAndY, f1: WritableXAndY }
undefined if the lines have a simple (transverse) intersection, or are parallel without overlap.
Otherwise, return the fractions at which each segment overlaps the other line:
- segment B maps to fractions in the range f0.x < f1.x on line A.
- segment A maps to fractions in the range f0.y < f1.y on line B.
