Question

这是我用搅拌机创建的椅子：

enter image description here

现在，当我使用Java3D显示它时，这就是我得到的：

为什么我的纹理没有出现在java中？这是我展示椅子的代码：

        SimpleUniverse universe = new SimpleUniverse(canvas);
        universe.getViewingPlatform().setNominalViewingTransform();
        universe.addBranchGraph(content);
    }

    public BranchGroup getScene()
    {
        BranchGroup group = new BranchGroup();

        Loader3DS loader = new Loader3DS();

        Scene scene = null;

        try

        BoundingSphere boundSphere = new BoundingSphere(new Point3d(0.0f, 0.0f, 0.0f), 200);
        rotator.setSchedulingBounds(boundSphere);
        objSpin.addChild(rotator);

        TransformGroup moveGroup = new TransformGroup();
        Transform3D move = new Transform3D();
        move.setTranslation(new Vector3f(0.0f, 0.0f, -20.0f));
        moveGroup.setTransform(move);
        moveGroup.addChild(objSpin);

        group.addChild(moveGroup);

        Background background = new Background(0.0f, 1.0f, 1.0f);
        background.setApplicationBounds(new BoundingSphere());
        group.addChild(background);

        Color3f light1Color = new Color3f(1.0f, 1.0f, 1.0f);

        DirectionalLight light1 = new DirectionalLight(light1Color, light1Direction);
        light1.setInfluencingBounds(bounds);
        group.addChild(light1);

        return group;
    }

    public static void main(String args[])
    {
        Frame frame = new MainFrame(new LoadAnObject(), 256, 256);
    }
}

我使用的文件格式是.3ds，这里是我从中获取加载程序的地方：

http://sourceforge.net/projects/java3dsloader/

如何让椅子的质地显示在java？

编辑：

我把我的椅子编成了.3ds文件而不是目标文件，我现在必须使用从这里得到的.3ds加载器：

http://sourceforge.net/projects/java3dsloader/

代码不会改变太多，而不是使用ObjectFile我现在使用Loader3DS

所以现在显然你可以看到转移的材料，而不是纹理，我如何让纹理显示出来？

Answer 1

Java显然不会加载纹理，除非它们是从图像生成的。我能够加载纹理的唯一方法是从图像映射纹理。我尝试了几种不同的格式，但我什么都没有。如果您打算在Java3D中尝试使用纹理，请确保使用图像映射纹理!!

为什么我的物体的纹理没有出现？
