The documents of ArcGIS API for JavaScript is great, plenty of examples and references. But it seems lack of how to extend the existing feature layer , how to create custom feature layers, renderers and symbols?
For example, when using a FeatureLayer with lot's of data in a MapView, it is loaded tile by tile (split of current mapview's extent), but when using in a SceneView, it is loaded page by page (serverside pagination). If I want to change the loading behavior of FeatureLayer in SceneView to tile by tile , I should create a custom feature layer, but I don't know how to start.
And the 3D symbol, it is too small for overview high level view, and too large for detail level level, If I want to maintain the 3D symbol 's size at fixed screen size , it seems I should create a custom renderer or symbol, but I don't now how to start too.
Any reply/suggestion is welcome!
