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!

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!
