lineSegmentXYUVOverlapUnbounded MethodStatic
Intersect two overlapping unbounded 2D lines.
lineSegmentXYUVOverlapUnbounded(a0: XAndY, aDir: XAndY, b0: XAndY, bDir: XAndY, tol: number = Geometry.smallMetricDistance): { f0: WritableXAndY, f1: WritableXAndY } | undefined
@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.
@see lineXYUVTransverseIntersection, lineSegmentXYUVIntersectionUnbounded
| Parameter | Type | Description |
|---|---|---|
| a0 | XAndY | start point of line A |
| aDir | XAndY | direction vector of line A; end point of line segment A is a0 + aDir |
| b0 | XAndY | start point of line B |
| bDir | XAndY | direction vector of line B; end point of line segment B is b0 + bDir |
| tol | number | overlap distance tolerance |
Returns - { f0: WritableXAndY, f1: WritableXAndY } | undefined
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.
