How to create a custom layer or find CustomLayerHost from mapbox ?

[D1maD1m0nd]

Hello. I want to create a custom layer for icons so that I can set the font and render, change the height, etc.
I found the examples below on the Internet, but I did not find the CustomLayerHost interface from the example
How can I make a similar example on Map libr (without C++)
version = 10.2.0

Please explain what you are trying to achieve instead of linking to proprietary code. We're very cautious not to look at proprietary code to not inadvertently violate copyright of Mapbox. I removed links to proprietary code in a Mapbox repo, thanks for understanding!

That said, you can find an example custom layer for Android here:

maplibre-native/platform/android/src/example_custom_layer.cpp

Line 126 in cd6a0ab

class ExampleCustomLayer : mbgl::style::CustomLayerHost {

Is it possible to make a custom layer in Java on openGl ES 20?
My task is to create a new layer to place icons on it and control their rendering, location and attributes

Yes this is possible, but you will have to use the 10.3.x MapLibre Native Android releases, we will upgrade to OpenGL ES 3.0 in 11.0.0.

You can show an example of creating a custom layer in Java and OpenGL ES for the Maplibre android SDK ('org.maplibre.gl:android sdk:10.3.0'). There is already an example on the site, but it uses some CustomLayerHost that I haven't found anywhere to use.
Or you can write an algorithm on how I should proceed to develop my own layer in OpenGL ES with Maplibre, I don’t quite understand where to start

Actually, a custom layer needs to be implemented using C++ at the moment.

But I doubt using a custom layer is needed for your use case. You certainly do not need it for icons. Can you share a bit more information?

I am working on a project where we place 3d models of a building on a map using polygons in the FillExtrusionLayer layer. There is a problem with placing icons above rooms in a building that are on high floors, because icons can only be placed on the plane of the map itself and they cannot be set height relative to ground level in SymbolLayer. And that's why I wanted to use a custom layer to solve this problem.
