How to integrate DEM models with Cesium for visualization

I want to visualize a terrain.
I have the dem models, raster files and vector files which i want to visualize and get a 3D terrain.
In the later stages I would like to apply routing algorithms which will take in parameters like buildup, rivers, length of road to output available paths that can be taken to reach from point A to point B.
Can someone please suggest me some resources which could be help me with this.
Any help is much appreciated!!

Hi there,

For terrain and imagery visualization, I would suggest getting started with our terrain and imagery tutorials respectively.

Routing can be incorporated in different ways, so it may be helpful to understand more details about your use case, but CesiumJS supports many standard data formats such as GeoJSON, KML, and CZML.
