I need to show a small territory 3D model on the Globe. I have a pack of orthos and pointcloud covering it. I chose Cesium + Geoserver WMS service to show orthos at a globe. Service imported in Cesium fine, but it flies over the surface. I'm using both Cesium Ellipsoid and Cesium Global Terrain and it flies over the surface. I have only orthos and DEM, Is there any method to create a 3D tiles from such data? Or I need to build my own terrain and use it like Cesium Terrain provider? Wich way will be better and faster?
