3D: distance to a geoemtry

Question

Hi!

How can i retrieve the distance (or something similar) of an object/geometry at my scene/sceneGraphicsView and the viewpoint/camera?

I want to use this distance to decide if the object has to be displayed in detail (it´s in front of my scene) or rough (it´s more or less far away at the horizon)....

I struggle using GeometryEngine::distance(gemeotry, currentViewpoint().targetGeometry)...

Can someone point me to the rigth direction?

Thx in advance!

Hi Elliot!

Thanks for your quick answer.

Unfortuately i mixed degree and radiant, so my results were confusing 😞

The approach you are suggesting seems to be fine with one small modification: i´m using distanceGeodetic.

Thanks a lot!

Hi there Norbert.

Maybe try something like :

GeometryEngine::distance(geometry, currentViewpoint().camera().location());

to get the distance between your geometry and the camera position. I'm not sure targetGeometry is quite what you're looking for.

You might also consider using a Distance Composite Symbol for this instead, which might suit your purposes without you having to manually program in the distance checking code.

Hope that helps.
