Clipping area in 2D and columbus view since release 1.18

Hello all,

i'm having an issue i can't quite understand, as far as i can see i get this issue since version 1.18, before this is not the case.

When switching to 2D or columbus view there is an artifact i think i can describe as circular transparent billboard which clips other primitives in the scene, for example a pointcollection or a rectangle. It can only be seen when having a primitive behind it because it clips it and only in 2D and columbus view.
Looking at the changes in 1.18 maybe some kind of billboard was introduced for the star burst example?
Here is a screenshot of columbus view from an angle where i can see the object is round (the clipping area changes depending on the camera angle):

The yellow area is just a simple rectangle primitive and in the middle is this clipping thing.
i hope you have some ideas of why this is happening.

Thanks for your help and time and this great library.

Kind regards,
Daniel

Thanks for reporting this Daniel! It could reproduce this bug in 1.17 but not in 1.16, so I’m guessing it was introduced by a change in the 1.17 release.
I wrote up an issue here: https://github.com/AnalyticalGraphicsInc/cesium/issues/3748

We should be able to look into it soon.

Thanks for the quick response and adding the issue with a much better description then mine :slight_smile: hopefully there is a nice solution for this as i always want to have the goodies and improvements of the new releases, but something like this does not allow me to use it.

Kind regards,
Daniel

Hi, im really sorry to go off topic here but the switching animations that can be seen in:
https://github.com/AnalyticalGraphicsInc/cesium/issues/3748
(3D -> CV; 2D -> 3D -> CV)
are so much nicer then the ones i get (also on your main site). Are you on a special branch or something? Where can i get those nice switching animations!

Oh yeah! Those look so much better, right?
Dan made those changes to the animation transitions recently and they will be available in the next release on April 1 =)
I was running the code off Master to make sure the problem wasn’t already fixed by something else we did since the last release.

Best,

Hannah

Daniel,

This bug was fixed and will be in the 1.20 release on April 1st.

Best,

Dan
