Question

请问如何让wall向下拉伸包围管线呢？代码原理是这样的，wblgl在三维场景中画矩形，然后根据每条边（line）添加wall，代码如下：

var redwall = viewer.entities.add({
    name: 'RedWall' + i,
    wall: {
        positions: Cesium.Cartesian3.fromDegreesArrayHeights(line),
        minimumHeights: [50, 50],
        material: Cesium.Color.RED,
    }
});

Answer 1

var a = viewer.entities.add({
                    name : 'Green wall from surface with outline'+8,
                    wall : {
                        positions : Cesium.Cartesian3.fromDegreesArrayHeights([-107.0, 43.0, 100,
                                                        -97.0, 43.0, 100,
                                                        -97.0, 40.0, 100,
                                                        -107.0, 40.0, 10,
                                                        -107.0, 43.0, 100]),
                        minimumHeights :[-1000,-1000,-1000,-1000,-1000],
                        material : Cesium.Color.GREEN,
                        outline : true
                    }
                });

您好，该代码可实现向下拉伸

解决啦，非常感谢~

你好，还想请问一下，webgl怎么设置wall的纹理贴图呢？

直接对material设置一个图片就可以了
