Method Detail

compare

public int compare(org.jzy3d.maths.PolygonArray p1,
                   org.jzy3d.maths.PolygonArray p2)

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))

getDistance

protected double getDistance(org.jzy3d.maths.PolygonArray p,
                             org.jzy3d.plot3d.rendering.view.Camera c)
