Is hillshading possible (with raster-dem files)?

[DiegoTheWolf]

Hallo,

i didn't find any source for DEM files. Is it possible, or will it be possible in the future, to use raster-DEM files for terrain height and therefore hillshading?

Thank you in advance!

Hello @DiegoTheWolf , OpenLayers and therefor VueLayers not supporting 3d maps. But the OpenLayers team provides additional lib ol-cesium that do this.

I'm not a big expert in this area, but seems like ol-cesium can work with DEM files. But you need some additional plugin for Cesium to serve DEM data. Here is a SO question that I found: https://gis.stackexchange.com/questions/150861/does-ol3-cesium-accept-dem-files

As for integration of ol-cesium with vuelayers, the example below shows how to run :

<template>
  <vl-map ... @created="mapCreated">
    <vl-view ... />
    ....
  </vl-map>
</template>

<script>
import OLCesium from 'olcs/OLCesium.js';
import * as Cesium from 'cesium';

export default {
  methods: {
    mapCreated (vm) {
        const ol3d = new OLCesium({map: ol2dMap}); // ol2dMap is the ol.Map instance
        const scene = ol3d.getCesiumScene();
        scene.terrainProvider = new Cesium.CesiumTerrainProvider({
            // here you can provide your own tileset url, but seems you need geoserver with a special plugin (check the so question above)
            url: '//cesiumjs.org/stk-terrain/tilesets/world/tiles'
        });
        ol3d.setEnabled(true);
    },
  },
}
</script>

I'm not sure if it will work without errors... I can't reproduce such demo anywhere on some public demo site like jsfiddle, because they don't allow to CORS for this tileset url and I don't have any other opportunity to deploy such setup myself. So it is just an example adopted from ol-cesium docs and I hope it should work
