Question

I run my first program with 3D graphics in java but it has one exception
please help me in solve that.
this is my code:

public class Test extends Applet {

public Test() {
    SimpleUniverse universe = new SimpleUniverse();
                    BranchGroup group = new BranchGroup();
                    group.addChild(new ColorCube(0.3));
                    universe.getViewingPlatform().setNominalViewingTransform();
                    universe.addBranchGraph(group);


}


}

 public static void main(String[] args) {
    // TODO code application logic here
   new Test();
}

}

and this is it’s error

Answer 1

Some bits of Java3D require native libraries to work.

See here for a description of what’s necessary.
