各位大师,帮我生成一个三维图 用java3d 或者jogl  我是图像菜鸟!!!

图像,就是图中所示,我用java 3d 写了一点,jogl 一点也没看懂

java 3d 代码:

package a;

public class lineShape extends Shape3D{
 private float vert[]=
 {
  -0.6f,0.4f,0.0f,       -0.6f,-0.4f,0.0f,    -0.2f,-0.4f,0.0f,
 };
 private float vert2[]=
 {
   0.5f,0.8f,0.1f,0.2f,0.4f,0.0f,         0.2f,-0.4f,0.0f,      0.6f,-0.4f,0.0f,
 };

 

private float color[]=
{
 0.0f,0.5f,1.0f,   0.5f,0.0f,1.0f,
 0.0f,0.8f,2.0f,   1.0f,0.0f,0.3f,
 0.0f,1.0f,0.3f,   0.3f,0.8f,0.0f,
 0.5f,0.3f,0.3f,   0.0f,0.4f,0.1f,
};
public lineShape()
{
 int sCount[]=new int[1];
  sCount[0]=3;
  LineStripArray line=new LineStripArray(8,LineStripArray.COORDINATES|LineStripArray.COLOR_3,sCount);

 //LineArray line=new LineArray(8,LineArray.COORDINATES|LineArray.COLOR_3);
 line.setCoordinates(0, vert);
 line.setColors(0, color);

 la.setLineAntialiasingEnable(true);

 ap.setLineAttributes(la);
 this.setGeometry(line);
 this.setAppearance(ap);
 
 int sCount2[]=new int[1];
 //曲线顶点数目
 sCount2[0]=4;
 LineStripArray line2=new LineStripArray(8,LineStripArray.COORDINATES|LineStripArray.COLOR_3,sCount2);

 la2.setLineWidth(5.0f);
 la2.setLineAntialiasingEnable(true);
 Appearance ap2=new Appearance();
 ap.setLineAttributes(la2);
 this.setGeometry(line2);
 this.setAppearance(ap2);
}
public static void main(String[] args){
    SimpleUniverse universe = new SimpleUniverse();
  BranchGroup group=new BranchGroup();

  group.addChild(shape);
  universe.getViewingPlatform().setNominalViewingTransform();
    // 把group加入到虚拟空间中
    universe.addBranchGraph(group);
}
}
