◆ intersects()

PRIVATE bool QgsRay2D::intersects ( const QgsLineSegment2D segment,
QgsPointXY intersectPoint 
) const

Finds the closest intersection point of the ray and a line segment.

If found, the intersection point will be stored in intersectPoint.

Returns true if the ray intersects the line segment.
