Can JGraphT java library be used for making 3D graphs -

-

basically have plot 3d undirected graph list of vertices.at present can plot undirected graph in 2d , have used following code this.

import java.awt.color; import java.awt.dimension; import java.awt.rectangle; import java.awt.geom.rectangle2d; import java.util.hashmap; import java.util.map;  import javax.swing.japplet; import javax.swing.jframe;  import org.jgraph.jgraph; import org.jgraph.graph.defaultgraphcell; import org.jgraph.graph.graphconstants;  import org.jgrapht.listenablegraph; import org.jgrapht.ext.jgraphmodeladapter; import org.jgrapht.graph.listenabledirectedgraph; import org.jgrapht.graph.defaultedge;   public class jgraphadapterdemo extends japplet { private static final color     default_bg_color = color.decode( "#fafbff" ); private static final dimension default_size = new dimension( 530, 320 );  //  private jgraphmodeladapter m_jgadapter;  /**  * @see java.applet.applet#init().  */ public void init(  ) {     // create jgrapht graph     listenablegraph g = new listenabledirectedgraph( defaultedge.class );      // create visualization using jgraph, via adapter     m_jgadapter = new jgraphmodeladapter( g );      jgraph jgraph = new jgraph( m_jgadapter );      adjustdisplaysettings( jgraph );     getcontentpane(  ).add( jgraph );     resize( default_size );      // add sample data (graph manipulated via jgrapht)     g.addvertex( "v1" );     g.addvertex( "v2" );     g.addvertex( "v3" );     g.addvertex( "v4" );      g.addedge( "v1", "v2" );     g.addedge( "v2", "v3" );     g.addedge( "v3", "v1" );     g.addedge( "v4", "v3" );      // position vertices nicely within jgraph component     positionvertexat( "v1", 50, 50 );     positionvertexat( "v2", 120, 120 );     positionvertexat( "v3", 200,200 );     positionvertexat( "v4", 20, 20 );      // that's there it!... }   private void adjustdisplaysettings( jgraph jg ) {     jg.setpreferredsize( default_size );      color  c        = default_bg_color;     string colorstr = null;      try {         colorstr = getparameter( "bgcolor" );     }      catch( exception e ) {}      if( colorstr != null ) {         c = color.decode( colorstr );     }      jg.setbackground( c ); }   private void positionvertexat( object vertex, int x, int y ) {     defaultgraphcell cell = m_jgadapter.getvertexcell( vertex );     map attr = cell.getattributes(  );     rectangle2d b = graphconstants.getbounds(attr);      graphconstants.setbounds( attr, new rectangle( x, y, b.out_bottom, b.out_top ) );      map cellattr = new hashmap(  );     cellattr.put( cell, attr );     m_jgadapter.edit( cellattr, null, null, null); } }

now want know can extend code , plot undirected graph in 3d using jgrapht library.is there else more useful me in fulfulling task other this.

i have implemented above task.i have not done using jgrapht library instead did using java 3d only.below code shows 3d undirected graph of tetrahedron made using java 3d.

import javax.media.j3d.appearance; import javax.media.j3d.boundingsphere; import javax.media.j3d.branchgroup; import javax.media.j3d.geometryarray; import javax.media.j3d.linestriparray; import javax.media.j3d.shape3d; import javax.media.j3d.transformgroup; import javax.vecmath.point3d; import com.sun.j3d.utils.behaviors.mouse.mouserotate; import com.sun.j3d.utils.universe.simpleuniverse;   public class test {  public test(){  simpleuniverse u=new simpleuniverse();   branchgroup group=new branchgroup();  point3d coords[] = new point3d[9];  appearance app=new appearance();  coords[0] = new point3d(0.5d, 0.5d, 0.5d); coords[1] = new point3d(1.0d, 0.5d, 0.5d); coords[2] = new point3d(0.5d, 0.5d, 0.5d); coords[3] = new point3d(0.5d, 1.0d, 0.5d); coords[4] = new point3d(0.5d, 0.5d, 0.5d); coords[5] = new point3d(0.5d, 0.5d, 1.0d); coords[6] = new point3d(1.0d, 0.5d, 0.5d); coords[7] = new point3d(0.5d, 1.0d, 0.5d); coords[8] = new point3d(0.5d, 0.5d, 1.0d);   int vertexcounts[] = {9};   linestriparray lines = new linestriparray(9,  geometryarray.coordinates, vertexcounts);   lines.setcoordinates(0, coords);  shape3d shape=new shape3d(lines , app);  //group.addchild(shape);  transformgroup objrotate = new transformgroup(); objrotate.setcapability(transformgroup.allow_transform_write); objrotate.addchild(shape);  mouserotate f1=new mouserotate(); f1.setschedulingbounds(new boundingsphere()); f1.settransformgroup(objrotate); group.addchild(f1);  group.addchild(objrotate);  u.addbranchgraph(group);  u.getviewingplatform().setnominalviewingtransform();  }  }

How to start daemon on android by adb -

can me please, head swollen... i trying run daemon on android emu/device command: adb -s <device_name> shell su -c /dir/daemon <port_number> but nothink happens, , no errors! if do: adb -s <device> shell and form shell cmdline: su -c /dir/daemon <port_number> than work fine. try use shell-script , run: adb -s <device_name> shell sh su -c /dir/script.sh <port_number> and try generate script qt code port number , use: adb -s <device_name> shell sh su -c /dir/script.sh but not helped... problem if enter adb shell previous run daemon - work. problem on different device/emu/iso_image different command format not work. example: adb -s <device_name> shell su -c /dir/daemon <port_number> // work @ emu, not @ iso and vice: adb -s <device_name> shell su -c "/dir/daemon <port_number>" // work @ iso etc. everybody can answer what's matter? sorry english adb shell su -c ...
