Question

我在cesium下可以使用的polyline volume，为啥在supermap下不能使用？

我在cesium下都可以用的代码，搬到superMap下，就不能使用了。哎！不知道咋回事，太深的挫败感！！

您好，您是想实现多段线柱体吗？通过entitty中polylineVolume是可以添加的。

function computeCircle(radius) {
    var positions = [];
    for (var i = 0; i < 360; i++) {
        var radians = Cesium.Math.toRadians(i);
        positions.push(new Cesium.Cartesian2(radius * Math.cos(radians), radius * Math.sin(radians)));
    }
    return positions;
}
var redTube = viewer.entities.add({
    name : 'Red tube with rounded corners',
    polylineVolume : {
        positions : Cesium.Cartesian3.fromDegreesArrayHeights([
            102.67773481610077, 31.071257883937033, 5000,
            102.74883646240747, 31.121299541997338, 5000,
            102.92726036147866, 31.08704848398098, 5000,
            102.84562112186255, 31.010046039747248, 5000
        ]),
        shape : computeCircle(100.0),
        material: Cesium.Color.WHITE,

    }
});
