Detailed Description

A convex hull builder that tries to create 2D hulls as accurately as possible. Used for offline processing.

Member Typedef Documentation

◆ Edges

using ConvexHullBuilder2D::Edges = Array<int>

◆ Positions

using ConvexHullBuilder2D::Positions = Array<Vec3>

Member Enumeration Documentation

◆ EResult

enum class ConvexHullBuilder2D::EResult

strong

Result enum that indicates how the hull got created.

Enumerator
Success	Hull building finished successfully.
MaxVerticesReached	Hull building finished successfully, but the desired accuracy was not reached because the max vertices limit was reached.

Constructor & Destructor Documentation

◆ ConvexHullBuilder2D()

ConvexHullBuilder2D::ConvexHullBuilder2D ( const Positions & inPositions )

explicit

Constructor

Parameters

inPositions Positions used to make the hull. Uses X and Y component of Vec3 only!

◆ ~ConvexHullBuilder2D()

ConvexHullBuilder2D::~ConvexHullBuilder2D ( )

Destructor.

Member Function Documentation

◆ Initialize()

ConvexHullBuilder2D::EResult ConvexHullBuilder2D::Initialize	(	int	inIdx1,
		int	inIdx2,
		int	inIdx3,
		int	inMaxVertices,
		float	inTolerance,
		Edges &	outEdges
	)

Takes all positions as provided by the constructor and use them to build a hull Any points that are closer to the hull than inTolerance will be discarded
