Camera FOV Serialisation

Question

The toJSON method on the ersi/Camera Object does not serialise the fov property of the camera.

I know I can just access the value from the object directly but I did experct the toJSON return to contain this value. Also the correspoding functionality in fromJSON.

Is this an oversight or by design?

Hi I am interested in being able to adjust the fov of the camera when moving between viewpoints for a landscape and visual assessment project which requires specific visualisations with the HFoVs often 90 and 53.5. I have tried with the following script for Viewpoint 2. I can adjust tilt and position but not fov. I have read through the above thread but not sure how to implement the changes I need to the following script. Many thanks in advance.

Yes, i currently serialise the viewpoint and use it in a similar way to the bookmarks in 2D.

It would be nice if the fov animated with the goTo function aswell.

Hi Jethro, thanks for your feedback, that's a good point, I'm currently discussing with my colleagues about adding the property to the `toJSON` method. Initially there was no platform support for this property, so we didn't serialize it.

How do you use the serialization in your application? do you want to save webscenes to the ArcGIS platform with different fields of view?
