Question

所以我要做的是将不同尺寸的盒子装入一个大容器中。我正在使用LAFF算法来执行此操作，并且我想使用Java3D可视化容器的完整加载计划。我的问题是，当我尝试为每个杠杆定位包装盒时，它们超过了容器的尺寸，而第二个水平的盒子没有出现在第一个盒子的顶部。我附上了一张新图片

这是我为Java3D中的打包过程编写的代码：

 VirtualUniverse myUniverse = new VirtualUniverse();
        Locale myLocale = new Locale(myUniverse);
        float p2 = 0;
        BranchGroup nodeRoot = new BranchGroup();
        nodeRoot=buildContentBranch(buildShape(x, y, z));

        //----------------------------------------
        Shape3D backShape = ((Box) buildShape(x, y, z)).getShape(Box.RIGHT);

          int rr = 2;
          System.out.println();
          float[] position = new float[3];
          geo.getCoordinates(rr, position);
          Vector3f pp = new Vector3f (position[0],position[1], position[2]);


        //--------------------------------------------------------
        GeometryArray geo=(GeometryArray)backShape.getGeometry();
        float[] position=new float[3];
        geo.getCoordinate(0, position);
        //geo.getCoordinate(1,position);
        //System.out.println(position[0]+" "+position[1]+" "+position[2]);
       Vector3f pp = new Vector3f (position[0]-0.2f,position[1]+0.3f, position[2]-0.1f);
        Color3f c1=new Color3f(0.7f, .15f, .15f);
        Color3f c2=new Color3f(0.7f, .15f, .15f);
        Color3f[] c=(Color3f[]) new Color3f[20] ; 

            c[0] =new Color3f(Color.getHSBColor(20.f, 30f, 2.f));
            c[1] =new Color3f(Color.BLUE);
            c[2] =new Color3f(Color.YELLOW);
            c[3] =new Color3f(Color.GREEN);
            c[4] =new Color3f(Color.WHITE);
            c[5] =new Color3f(Color.CYAN);
            c[6] =new Color3f(Color.LIGHT_GRAY);
            c[7] =new Color3f(Color.PINK);
            c[8] =new Color3f(Color.RED);
            c[9] =new Color3f(Color.DARK_GRAY);
            c[10] =new Color3f(Color.MAGENTA);
            c[11] =new Color3f(Color.getHSBColor(0.2f, 0.15f, 2.f));
            c[11] =new Color3f(Color.getHSBColor(0.8f, 0.1f, 15.f));
            c[13] =new Color3f(Color.ORANGE);
            c[11] =new Color3f(Color.getHSBColor(1.f, 0.8f, 2.f));



    //--------------------------------------------------------------------- 
        int i=0;
                for (Level level : levels2) {
                  for (Items b : level.packedBoxes) {

                Transform3D transform = new Transform3D();
                transform.setTranslation(pp);
                Box ProductBox = addProductBox(b.dimension.get("length"),b.dimension.get("breadth")
                        ,b.dimension.get("height"),c1, c2,c[i],c[i]);
                Transform3D rotateCube = new Transform3D();
                rotateCube.set(new AxisAngle4d(1.0, 1.0, 0.0, Math.PI / 4.0));
                TransformGroup rotationGroup = new TransformGroup(rotateCube);
                TransformGroup TranslateGroup = new TransformGroup(transform);
                TranslateGroup.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
                rotationGroup.addChild(ProductBox);
                TranslateGroup.addChild(rotationGroup);
                nodeRoot.addChild(TranslateGroup);
                //get the coordinates of the new box 
                Shape3D shape = ProductBox.getShape(Box.FRONT);

            position[0]-= b.dimension.get("length");
            p2=boxBig.dimension.get("height");
           if (position[0]-x>0) {
             position[1]+= b.dimension.get("breadth");

            }
            if (y-position[1]<0)  
            {
                position[2]+=p2;
            }
        i++;
         Vector3f pp2 = new Vector3f (position[0],position[1], position[2]);
         pp=pp2;

       System.out.println("pppppppp  " +pp);
        }
            }
            myLocale.addBranchGraph(nodeRoot);
            setTitle("Container Loading");
            setSize(1000,1000);
            setLayout(new BorderLayout());
            add("Center", canvas);
            setVisible(true);
            myLocale.addBranchGraph(buildViewBranch(canvas));

我有8个盒子。我试图知道我的代码有什么问题，但我无法弄清楚问题出在哪里。谁能帮我这个？谢谢。

我看到的第一个错误是

   position[0]+= b.dimension.get("length");
   p2=boxBig.dimension.get("height");

           System.out.println("position 0 " +position[0]);
        //g.getCoordinate(1,position);
   g.getCoordinate(2,position);

你推进了位置，但是你重新读了它将覆盖。

然后pp（如果你用它来定位第二个对象等）似乎没有在内循环内进行。

现在就是这样。

更新后：我看到lightGray项目被隐藏，所以它必须很小;白色突出两个盒子。也许你用来推进这个位置的长度可能是＆＃34;广度＆＃34;。

使用Java3D进行容器打包
