There has been a long standing problem to visualize two different terrains in a CesiumJS app.
In CesiumJS API, I know that ‘CesiumTerrainProvider’ accepts only one terrain tileset in a viewer construct. Due to this, it’s known to be impossible visualizing two different tilesets in a single CesiumJS app session.
However, in many of customer use cases, there are frequent requests those need to overcome this limitation. For example, in a building construction site, let’s think about an as-is terrain. On the other hand, according to a construction plan, an uphill ground is going to cut. And, the customer would like to place a planned building tileset and compare the perspective views before and after the construction. In order to achieve it, how can I compare the terrains between as-is and the cut. A similar need exists for the fill terrain as well.
Could any Cesium staff or community members answer this question?
Many thanks in advance,
