Terrain for non-geographic maps

[Sgambe33]

I'm developing a website to display heatmaps of player movements in a game map. Obviously I am not using geographic coordinates but I managed to load the basemap and display the heatmap.

I was wondering if given a png heightmap is possible to apply it directly without tiling. I tried with deck.gl terrain layer but the two thing are not compatible it seems: no maplibre's heatmap over deck.gl's terrain. Is there a solution or I'm better off to keep it 2d? Thanks

The terrain feature in maplibre-gl-js is only supported using raster-dem source, which is tiled, so you'd need to create that kind of source in order to use it with terrain, you could also use it for hill shading, so that's a nice benefit.
There some tools to convert heightmap to terrainRGB tiles out there...

So basically I have to implement a way to load a single image instead of a tiled service right?

You might be able to use addProtocol for that, load the image to memory and split it on the client side to tiles as needed.
But generally, yes, you'd need to implement it.
