Question

看到10i更新的类里新增了HeatMap类,根据api中的实例调用,提示缺少构造参数.能不能给一个准确的使用说明

您好，需要添加context，可以这样写

var bounds = new Cesium.BoundingRectangle(minX, minY, maxX - minX, maxY - minY);
                    var heatMap = new Cesium.HeatMap({
                        intensityRange: new Cesium.Cartesian2(minDepth, maxDepth),
                        // intensityRange: new Cesium.Cartesian2(0, 1),
                        bounds: bounds,
                        context: scene._context
                    });
                    scene._primitives.add(heatMap);

                    heatMap.setData(datas);
