Member Function Documentation

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.
