osgEarth读取矢量问题

hello!

利用osgViewer读取osgEarth的tests文件夹feature_stencil_line_draping.earth，可是读取的数据图像出现淡黄色模糊的景象，而且矢量也不可见(见图feature_stencil_line_draping)，
<!--
osgEarth Sample
This one demonstrates how to "drape" line data on the map using a
stenciling technique.
-->
<map name="Feature Stencil Demo" type="round">
    <image name="world" driver="gdal">
        <url>../data/world.tif</url>
    </image>
   
    <model name="states" driver="feature_stencil">
        <!-- Configure the OGR feature driver to read the shapefile.
             Convert the goemetry to lines, and apply a small buffer
             to give the lines thickness. -->
            
        <features name="world" driver="ogr">
            <url>../data/world.shp</url>
            <ogr_driver>ESRI Shapefile</ogr_driver>
        </features>
        
        <geometry_type>line</geometry_type>
               
        <!-- This driver uses the "stroke-width" property below to define
             the width (in data source coordinated) of the draped lines.
             In this case the units are degrees. -->
            
        <style type="text/css">
            world {
               stroke: #ffff00;
               stroke-opacity: 0.5;
               stroke-width: 0.1;
            }            
        </style>
        
    </model>
  
</map>
而在读取feature_stencil_polygon_draping.earth时，出现橙色模糊景象，没有矢量出现(如图feature_stencil_polygon_draping)。请问各位这个问题如何解决？谢谢

请问你问题解决了吗，我的没有这种模糊的景象，但矢量图也不可见
