In agent2D3.1.1 , I use base Interface too compute VoronoiDiagram point,
for exeample
:{
VoronoiDiagram M_pass_voronoi_diagram;

const Rect2D rect = Rect2D::from_center( 0.0, 0.0,
ServerParam::i().pitchLength() - 10.0,
ServerParam::i().pitchWidth() - 10.0 );


M_pass_voronoi_diagram.clear();

const SideID our = wm.ourSide();


const AbstractPlayerCont::const_iterator end = wm.allPlayers().end();
for ( AbstractPlayerCont::const_iterator p = wm.allPlayers().begin();
p != end;
++p )
{

if ( (*p)->side()!=wm.ourSide())
{
M_pass_voronoi_diagram.addPoint( (*p)->pos() );
}

}
// our goal
M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5, 0.0 ) );
// M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5,
// - ServerParam::i().goalHalfWidth() ) );
// M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5,
// + ServerParam::i().goalHalfWidth() ) );

// opponent side corners
M_pass_voronoi_diagram.addPoint( Vector2D( + ServerParam::i().pitchHalfLength() + 10.0,
- ServerParam::i().pitchHalfWidth() - 10.0 ) );
M_pass_voronoi_diagram.addPoint( Vector2D( + ServerParam::i().pitchHalfLength() + 10.0,
+ ServerParam::i().pitchHalfWidth() + 10.0 ) );

M_pass_voronoi_diagram.setBoundingRect( rect );


#if 0
// our goal
M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5, 0.0 ) );
// M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5,
// - ServerParam::i().goalHalfWidth() ) );
// M_pass_voronoi_diagram.addPoint( Vector2D( - ServerParam::i().pitchHalfLength() + 5.5,
// + ServerParam::i().goalHalfWidth() ) );

// opponent side corners
M_pass_voronoi_diagram.addPoint( Vector2D( + ServerParam::i().pitchHalfLength() + 10.0,
- ServerParam::i().pitchHalfWidth() - 10.0 ) );
M_pass_voronoi_diagram.addPoint( Vector2D( + ServerParam::i().pitchHalfLength() + 10.0,
+ ServerParam::i().pitchHalfWidth() + 10.0 ) );

M_pass_voronoi_diagram.setBoundingRect( rect );
#endif

M_pass_voronoi_diagram.compute();


std::vector<Vector2D> *target_map=new std::vector<Vector2D>;
// M_pass_voronoi_diagram.getPointsOnSegments(3,3,target_map);;
double best_eva=0;
Vector2D best_point=target_point;
// std::cout<<(*target_map).size()<<std::endl;

VoronoiDiagram::Vector2DCont VN_Point;
VN_Point=M_pass_voronoi_diagram.resultPoints();
std::ofstream fout("vorongraph.txt",std::ios::app);

for (VoronoiDiagram::Vector2DCont ::const_iterator it =VN_Point.begin(); it!=VN_Point.end(); it++)
{

fout<<"clycle"<<wm.time().cycle()<<"*******"<<(*it)<<std::endl;

if ( (*it).absX()>52||(*it).absY()>33)
{
continue;
}

target_map->push_back((*it));

}

but I find the point diffrent with soccerwindow2 _voronoi_diagram point?
It 's a bug in agent2d3.1.1?
