Constructor Details

BoundaryProjector2S

BoundaryProjector2S(Point2S point)

Simple constructor.

Parameters:

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

Method Details

disambiguateClosestPoint

protected Point2S disambiguateClosestPoint(Point2S target,
 Point2S a,
 Point2S 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<Point2S, RegionBSPTree2S.RegionNode2S>

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
