Cesium Sensor

I am trying to run cesium sensor in cesium-1.17.
I get error “Length” attribute is not defined.

How can it be fixed

Hello did you check https://github.com/kaktus40/cesium-sensors

Great. It works. Thanks

How can we edit a sensor. I created a rectangular sensor and now want to change its radius and x y angles.
I created sensor using this example https://github.com/AnalyticalGraphicsInc/cesium-sensors/tree/master/Examples/api.html

Thanks it works.
Now I want sensor not to bypass if I place any gltf or shape object in place. How can this be achieved!

https://github.com/kaktus40/cesium-sensors
dist directory can not find…

also,it has no cesium.js file,what should it makes it work? thanks.

how can i show the intersection of the sensor with gltf models or objects and stop the sensor passing through the object,
i used showIntersection = true, but it is not working.

Hi sankin,

The cesium-senor plugin has been deprecated for a while, so we won’t be providing support or fixing bugs. Sorry!

Thanks,

Gabby
