【解决办法】只有当开启地下相对模式且相机高度不大于 10,000 米时，设置添加挖方区域几何对象效果才可见
GeoRegion3D excavationRegion = (GeoRegion3D)e.getGeometry();
GeoStyle3D geoStyle3D = new GeoStyle3D();
geoStyle3D.setBottomAltitude(0);
geoStyle3D.setExtendedHeight();
geoStyle3D.setSideTextureFiles(new String[] {});
geoStyle3D.setTilingU();
geoStyle3D.setTilingV();
geoStyle3D.setTopTextureFile();
geoStyle3D.setTopTilingU();
geoStyle3D.setTopTilingV();
excavationRegion.setStyle3D(geoStyle3D);
sceneControl.getScene().getGlobalImage().addExcavationRegion(excavationRegion, "ExcavationRegion");
