Detailed Description

A visitor that visits INTERSECTABLE_GEOM variant objects with another (which is held as state: m_otherGeometry).

This provides a unified way to intersect any supported geometry with any other supported geometry.

Constructor & Destructor Documentation

INTERSECTION_VISITOR() [1/2]

INTERSECTION_VISITOR::INTERSECTION_VISITOR	(	const INTERSECTABLE_GEOM &	aOtherGeometry,
		std::vector< VECTOR2I > &	aIntersections )

Parameters

aOtherGeometry	The other geometry to intersect the visited geometry with.
aIntersections	A vector to store the intersections in. Does not have to be empty, the visitor will append to it.

Definition at line 431 of file intersection.cpp.

References m_intersections, and m_otherGeometry.

INTERSECTION_VISITOR() [2/2]

INTERSECTION_VISITOR::INTERSECTION_VISITOR	(	const INTERSECTABLE_GEOM &	aOtherGeometry,
		std::vector< VECTOR2I > &	aIntersections,
		INTERSECTION_CONTACT &	aContact )

Parameters

aContact

Receives how the geometries meet. Flags are only set, never cleared, so one contact accumulates across visits.
