Cesium之面entity的材料

1.代码

// 1.
entity.polygon.material = new Cesium.GridMaterialProperty({
  color: Cesium.Color.fromCssColorString(color),
  cellAlpha: 0.3,
  lineCount: new Cesium.Cartesian2(8, 8),
  lineThickness: new Cesium.Cartesian2(2.0, 2.0),
});
// 2.
$.getJSON('../../../data/china.json', function (result) {
  for (var i = 0, len = result.features.length; i < len; i++) {
    addBoundary(result.features[i]);
  }
});
// 墙效果
function addBoundary(feature) {
  var coordinates = feature.geometry.coordinates[0];
  var height = 800;
  var positions = [];
  var minimumHeights = [];
  var maximumHeights = [];
  for (var i = 0, len = coordinates.length; i < len; i++) {
    positions.push(
      Cesium.Cartesian3.fromDegrees(coordinates[i][0], coordinates[i][1])
    );
    maximumHeights.push(height * 150);
    minimumHeights.push(0);
  }
  var en = viewer.entities.add({
    wall: {
      positions: positions,
      maximumHeights: maximumHeights,
      minimumHeights: minimumHeights,
      material: new mars3d.AnimationLineMaterialProperty({
        // 动画线材质
        color: new Cesium.Color.fromCssColorString('#ADADAD'),
        duration: 5000, // 时长，控制速度
        url: '../../../images/fence.png',
        repeat: new Cesium.Cartesian2(5, 1),
      }),
      distanceDisplayCondition: new Cesium.DistanceDisplayCondition(2000),
    },
  });
}
