func ClosestHitAlongSegment ¶
func ClosestHitAlongSegment(ax, ay, bx, by, hitRadius float64, each func(yield func(x, y float64, id uint64))) (id uint64, ok bool)
ClosestHitAlongSegment finds the candidate whose center is closest to segment AB among those within hitRadius. each should call yield(x, y, id) for every candidate. Returns the winning id.
func DistPointSegment ¶
DistPointSegment returns distance from P to the closest point on segment AB.
