White spots between tiled model vertices

Hi,

we have white dots and lines appearing between 3D tiled dataset, is there any way to get rid of them?

Welcome to the community! Thank you for sharing this issue with us :grinning: :rocket:

I have noticed this issue in the past - are you currently using Cesium ion to stream your 3D Tiles into CesiumJS?

Hi, thank you for reply. We do not use Cesium Ion but custom tile server.

@samoo

Thanks for the information. Do you think that it is possible that the error is with your custom tile server? One quick sanity check would be to try using Cesium ion and see if you get the same issue.

Sure, I’m uploading it and will get back to you when I will check it.

Sounds good :+1:

Nah, it is doing also on Ion, feel free to check - assetID 653420, it was generated using Agisoft Metashape.

Isn’t this related to anti-aliasing with the confines of the data visualized? I know a few people have looked into the issue to have a better anti-aliasing, but I don’t know where that’s up to.

Cheers,

Thank you Alex for pointing me towards anti-aliasing. I was able to improve situation a bit using viewer.scene.postProcessStages.fxaa.enabled = true;

but still I would like to know if there is better way how to mitigate this problem.

Thank you all.

@samoo

I believe that we have suggested that community members use

viewer.scene.postProcessStages.fxaa.enabled = true;

in the past. We are currently working on MSAA for CesiumJS. The implementation should be complete in the near future. MSAA would improve our anti-aliasing for thin geometries such as telephone wires and polylines. It might also help resolve the issue that you are currently experiencing.
