FlowWallMaterialProperty

new FlowWallMaterialProperty(options) → {Object}

Examples

1. Entity 使用材质
  let material = new Cesium.FlowDigitalMaterialProperty() // 默认参数
       let entity = viewer.entities.add({
           position: Cesium.Cartesian3.fromDegrees(117.090795612294, 31.14224105521026, 50),
           plane: {
               plane: new Cesium.Plane(Cesium.Cartesian3.UNIT_Y, 0),
               dimensions: new Cesium.Cartesian2(1000, 50),
               material: material
           }
       })

 

2. Primitive 使用材质
       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, 50))
       let scaleMatrix = Cesium.Matrix4.fromScale(new Cesium.Cartesian3(1000, 50, 1))
       let rotationMatrix = Cesium.Matrix4.fromRotationTranslation(
           Cesium.Matrix3.fromRotationX(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.FlowWallMaterialType)
           }),
           modelMatrix: eunMatrix
       }));
