What is the current behavior?

#11374
While using the Street Smart plugin on 3D, the WFS call was not appropriately made at a tilted camera angle.

What is the new behavior?

• A new Strategy was introduced, named "tile" for the WFS layer, which
  • dynamically creates and manages custom tiles in 3d, and calls the WFS api on each tile
  • Same on OpenLayers, but OpenLayers itself manages the tiles; we only needed to give tileSize
• After the new strategy, in 3d, also in any tilt camera angle, api is called, and are rendered after the view is changed
• On Streetview of the CYCLOMEDIA, on level 17, tiles start to be created in 3d

Breaking change

• Yes, and I documented them in migration notes
• No

Other useful information

1. As extent was being sent only to Server type: no-vendor on both openlayers and cesium, so 'tile' strategy for wfs is only for no-vendor.
2. As for the "tile" strategy, features are managed on the Cesium billboard; on Cesium, only WFS with point features will be managed. But for OpenLayers, the tile strategy works for any geometric type.
3. For mark and icon of symbolizerToPrimitives, src is used instead of image for better performance.
4. From our last call, terrainProvider undefined in some cases was solved after the cleanup; now we always get a terrain provider for Street View WFS.
5. setStyleFunction on web/client/utils/cesium/TiledBillboardCollection.js is tested programmatically. Since we agreed to define tiledPrimitive inside the add function, and also not returned from the add function, we dont have access to it in update method. If declared before the add function and returned by the add function, it can be used to update the style inside the update method of WFSLayer.

       // update style for tile strategy
       if (newOptions.strategy === 'tile' && !isEqual(newOptions.style, oldOptions.style)) {
           layer.tiledPrimitive.setStyleFunction(newOptions.style);
        }
   

   Since for street view, a dynamic styling update is not required, setStyleFunction will only remain inside TiledBillboardCollection, which may be used later.
