Java 点位置标记的绘制顺序

有没有办法确定“世界风”中点位置标记的绘图顺序

即使在Placemark B和音频Placemark的顺序中，也可以通过在特定的缩放级别移动鼠标来更改：

到目前为止，我已经尝试：

• 将点放置标记添加到单独的图层
• 使用

  RenderableLayer.setRenderables

  而不是

  RenderableLayer.addRenderable

change

orderedRenderables

from

protected PriorityQueue<OrderedRenderableEntry> orderedRenderables =
    new PriorityQueue<OrderedRenderableEntry>(100, new Comparator<OrderedRenderableEntry>()
    {
        public int compare(OrderedRenderableEntry orA, OrderedRenderableEntry orB)
        {
            double eA = orA.distanceFromEye;
            double eB = orB.distanceFromEye;

            return eA > eB ? -1 : eA == eB ? (orA.time < orB.time ? -1 : orA.time == orB.time ? 0 : 1) : 1;
        }
    });
