Hello community, I’m drawing a viewshed with distance, vertical Angle and horizontal angle and we can change distance, vertical Angle and horizontal angle dynamically but I want to change my position dynamically and viewshed change according. see if somebody can help.
Hi @yogimlim
Is your sensor attached to an Entity? If so, moving the entity should move the sensor along with it. It would be helpful if you could share a code sample or a Sandcastle demonstrating the issue.
Thanks,
Sam.
@sanjeetsuhag thanks for your reply…
I am using 可视域分析
library for reference
and tileset json to create Cesium.Cesium3DTileset
not using any other sensor
Hi @yogimlim ,
I have the same problem, my viewshed functionality is only working with “static” position.
Maybe we can’t combine shadowMap + customShaders with a CallBackProperty (dynamic position).
But if you destroy everything and rebuild it with the new position, everytime the positions changes, it should work (at least in my theory 
). It wouldn’t be the most streamlined approach, though.
Best, Lennart
