Question

代码如下：

Gloabviewer = new Cesium.Viewer('cesiumContainer');

var initialScanColor = "2263e6";

    Gloabviewer.scene.scanEffect.show = true;

    Gloabviewer.scene.scanEffect.centerPostion = new Cesium.Cartesian3.fromDegrees(121.485457781151,31.240925443989802,3.0);

    Gloabviewer.scene.scanEffect.mode = Cesium.ScanEffectMode.LINE;

    Gloabviewer.scene.scanEffect.color = cesium.Color.fromCssColorString(initialScanColor);

    Gloabviewer.scene.scanEffect.speed = 3;

    var dir = new Cesium.Cartesian3();

    var startPosition = new Cesium.Cartesian3.fromDegrees(121.46995861055099,31.236599929777405,3.0);

    Cesium.Cartesian3.subtract(startPosition, Gloabviewer.scene.scanEffect.centerPostion, dir);

    Gloabviewer.scene.scanEffect.lineMoveDirection = dir;

为什么执行报错？

为An error occurred while rendering.  Rendering has stopped.

Answer 1

viewer.scene.scanEffect.show = true;
var pos = new Cesium.Cartesian3.fromDegrees(refLayer.lon,refLayer.lat,10.0);
viewer.scene.scanEffect.centerPostion = pos;

如果只是简单的扫描线的话，只需要设置这几个条件就可以了

Answer 2

你好，请问这个报错解决了吗，我也遇到了这个问题，如下图所示：
