Hi. I’d like to mark some areas of terrain like the photo I upload here. The marking is sticked with the terrain as you can see but I still don’t find any solution still now.
Actually, this scene is generated by Google Earth with *.shp file but when I tried to adopt this to Cesium Ion by converting(SHP to GeoJson), it only shows up 2D map.
Is there any solution to show marking in 3D maps that stick to the terrain?
