flood simulation

Hi, is there a way to render elevation data for water so it seems like flood simulation?

I think the easiest way to do this would be to define a semi-translucent polygon as your water level and move that to the desired height.

There’s an example for programmatically creating a polygon here: https://sandcastle.cesium.com/index.html?src=Polygon.html

Note that you might need to disable the logarithmic depth buffer if your water polygon covers a large area, see: https://github.com/AnalyticalGraphicsInc/cesium/issues/6573
