RadarSpreadMaterialProperty

new RadarSpreadMaterialProperty(options) → {Object}

Examples

1. Entity 使用材质 Plane为例
      let material = new Cesium.RadarSpreadMaterialProperty() // 默认参数
      let entity = viewer.entities.add({
          position: Cesium.Cartesian3.fromDegrees(117.090795612294, 31.14224105521026, 1),
          plane: {
              plane: new Cesium.Plane(Cesium.Cartesian3.UNIT_Z, 0.0),
              dimensions: new Cesium.Cartesian2(1000, 1000),
              material: material
          }
      })

2. Primitive 使用材质 Plane为例
      const instance = new Cesium.GeometryInstance({
          geometry: new Cesium.PlaneGeometry({
              vertexFormat: Cesium.VertexFormat.DEFAULT
          })
      });
      let eunMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(
          Cesium.Cartesian3.fromDegrees(117.090795612294, 31.13224105521026, 1))
      let scaleMatrix = Cesium.Matrix4.fromScale(new Cesium.Cartesian3(1000, 1000, 1))
      let rotationMatrix = Cesium.Matrix4.fromRotationTranslation(
          Cesium.Matrix3.fromRotationZ(Cesium.Math.toRadians(90)));
      Cesium.Matrix4.multiply(eunMatrix, rotationMatrix, eunMatrix)
      Cesium.Matrix4.multiply(eunMatrix, scaleMatrix, eunMatrix)
      viewer.scene.primitives.add(new Cesium.Primitive({
          geometryInstances: instance,
          appearance: new Cesium.MaterialAppearance({
              material: Cesium.Material.fromType(Cesium.Material.RadarSpreadMaterialType)
          }),
          modelMatrix: eunMatrix
      }));
