abstract Segments(Array<Segment>)

package h2d.col

from Array<Segment> to Array<Segment>

An abstract over the list of Segments. Alternative representation of a polygon.

Segments must be connected to form a complete polygonal shape. Provides a more efficient distance calculus.

Variables

@:implread onlylength:Int

The amount of segments in the polygon.

@:implread onlysegments:Array<Segment>

The underlying Array of segments.

Methods

@:implcontainsPoint(p:Point, isConvex:Bool):Bool

Tests if Point p is inside this Segments.

Parameters:

p

The Point to test against.

isConvex

Use simplified collision test suited for convex polygons. Results are undefined if polygon is concave. Note: Currently only convex check is implemented and using non-convex test results in an exception.

@:implinlinedistance(p:Point):Float

Returns distance from the Segments to the Point p.

@:impldistanceSq(p:Point):Float

Returns squared distance from the Segments to the Point p.

@:implproject(p:Point):Point

Projects Point p onto closest Segment in Segments and returns new Point with projected position.

@:impltoPolygon():Polygon

Converts this Segments to a Polygon.
