@Jacky Thank you for your answer.
Now I understand better how that works.I hadn’t noticed that this ViewShed3D method is external in the project (I thought its a Cesium built it feature).
Yes its using PostProcessStage but the source code is minified and a little bit hard to understand whats happening there.
I will be helpful if somebody else could suggest a solution for my questions:
- Looking for a way to create 3d ViewShed Analysis as shown in the screenshot (get how many % is hidden and visible from selected point)
