如何动态更改使用 RajawaliVR 渲染的图像

How to dynamically change the image rendered using RajawaliVR

public class MyRenderer extends RajawaliCardboardRenderer 
{
    public MyRenderer(Context context) 
    {
        super(context);
    }

    @Override
    public void initScene() {
    Log.d("debug1","initScene()");
    Sphere sphere = createPhotoSphereWithTexture(new Texture("photo",R.drawable.image));
    getCurrentScene().addChild(sphere);
    getCurrentCamera().setPosition(Vector3.ZERO);
    getCurrentCamera().setFieldOfView(75);
}

private static Sphere createPhotoSphereWithTexture(ATexture texture) {

    Material material = new Material();
    material.setColor(0);

    try {
        material.addTexture(texture);
    } catch (ATexture.TextureException e) {
        throw new RuntimeException(e);
    }

    Sphere sphere = new Sphere(50, 64, 32);
    sphere.setScaleX(-1);
    sphere.setMaterial(material);
    return sphere;
  }
}

目前在 RajawaliVR 库中预加载了一个固定图像。 用于设置图像的方法在开始时只调用一次。 我想随意更改图像。任何熟悉使用 rajawaliVR 库的人都会知道我在问什么,提前致谢。

得到解决方案,您可以动态更改对象的图像纹理,比如在某些外部触发器上,然后您可以使用此代码示例。
只要触发器被触发,您就可以调用 changeImage 方法。 不要忘记在 RajawaliCardboardRenderer 中声明方法 changeImage。 在 MyRenderer 对象上调用 changeImage 方法。

public class MyRenderer extends RajawaliCardboardRenderer 
    {
       public MyRenderer(Context context) 
       {
          super(context);
       }  

    @Override
    public void initScene() {
    Log.d("debug1","initScene()");
    Sphere sphere = createPhotoSphereWithTexture(new Texture("photo",R.drawable.image));
    getCurrentScene().addChild(sphere);
    getCurrentCamera().setPosition(Vector3.ZERO);
    getCurrentCamera().setFieldOfView(75);
    }

    private static Sphere createPhotoSphereWithTexture(ATexture texture) {

    Material material = new Material();
    material.setColor(0);

    try {
        material.addTexture(texture);
    } catch (ATexture.TextureException e) {
        throw new RuntimeException(e);
    }

    Sphere sphere = new Sphere(50, 64, 32);
    sphere.setScaleX(-1);
    sphere.setMaterial(material);
    return sphere;
    }

    public void changeImage()
    {
       Log.d("debug1", "" + getCurrentScene().getNumChildren());
        ArrayList<Object3D> objectList = getCurrentScene().getChildrenCopy();
        Material material = objectList.get(0).getMaterial();
        for (ATexture texture : material.getTextureList())
        {
            material.removeTexture(texture);
            texture = null;
        }

        Texture t = new Texture("sphereTexture",R.drawable.newImage);
        t.shouldRecycle(true);
              try {
                  material.addTexture(t);
              }
              catch (Exception e){e.printStackTrace();}

    }

    }
