Question

使用产品：iserver 10i 操作系统：win7 x64
数据类型： s3m
问题详细描述：按照demo开启了扩散扫描但是扩散的时候 不能经过轮廓看起来像是在2D底图上扩散
问题重现步骤：
我的效果demo的效果

代码：
 

     var entities = viewer.entities.values;
                    for (var i = 0; i < entities.length; i++) {
                        if (entities[i].polyline) {
                            entities[i].polyline.show = false;
                        }
                    }
                    viewer.scene.scanEffect.show = true; 
                    viewer.scene.scanEffect.mode = Cesium.ScanEffectMode.CIRCLE; 
                    viewer.scene.scanEffect.centerPostion = pos;
                    viewer.scene.scanEffect._period = 10000;
                    viewer.scene.scanEffect.color = Cesium.Color.fromCssColorString('#772e17')
                    viewer.scene.scanEffect.speed = 200;

                    viewer.scene.colorCorrection.saturation = 1000.9;
                    viewer.scene.colorCorrection.brightness = 120.8
                    viewer.scene.colorCorrection.contrast = 100.0;
                    viewer.scene.colorCorrection.hue = 100.0;

webgl版本是是否一致，可以将代码复制进官网示例中进行测试
