All Implemented Interfaces:

java.util.Comparator<AbstractDrawable>

public class BarycentreOrderingStrategy
extends AbstractOrderingStrategy

The BarycentreOrderingStrategy compare two AbstractDrawables by computing their respective distances to the Camera, which must be referenced prior to any comparison.

Modifier and Type	Method and Description
int	compare(AbstractDrawable d1, AbstractDrawable d2) Operation must be: symetric: compare(a,b)=-compare(b,a) transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0 true if all Drawables and the Camera don't change position! consistency?: compare(x, y)==0 implies that sgn(compare(x, z))==sgn(compare(y, z))
double	score(AbstractDrawable d) Returns a score for ranking this drawable among other drawables of the scenegraph.

Operation must be: symetric: compare(a,b)=-compare(b,a) transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0 true if all Drawables and the Camera don't change position! consistency?: compare(x, y)==0 implies that sgn(compare(x, z))==sgn(compare(y, z))

score

public double score(AbstractDrawable d)

Description copied from class: AbstractOrderingStrategy
