您好,您可以在idesktop中针对三维线缓存设置特效效果——带箭头。也可以在前端中设置线的样式为PolylineArrowMaterialProperty,如
var purpleArrow = viewer.entities.add({
name : 'Purple straight arrow at height',
polyline : {
positions : Cesium.Cartesian3.fromDegreesArrayHeights([-75, 43, 500000,
-125, 43, 500000]),
width : 50,
followSurface : false,
material : new Cesium.PolylineArrowMaterialProperty(Cesium.Color.PURPLE)
}
});参考范例http://support.supermap.com.cn:8090/webgl/examples/webgl/editor.html#Polyline
