Constructor Details

BoundaryProjector2D

BoundaryProjector2D(Vector2D point)

Simple constructor.

Parameters:

point - the point to project onto the region's boundary

Method Details

disambiguateClosestPoint

protected Vector2D disambiguateClosestPoint(Vector2D target,
 Vector2D a,
 Vector2D b)

Method used to determine which of points a and b should be considered as the "closest" point to target when the points are exactly equidistant.

Overrides:

disambiguateClosestPoint in class AbstractRegionBSPTree.BoundaryProjector<Vector2D, RegionBSPTree2D.RegionNode2D>

Parameters:

target - the target point

a - first point to consider

b - second point to consider

Returns:

which of a or b should be considered as the one closest to target
