Hi all! It was great meeting many of you at the Cesium Conference last week! While I was there, I took the opportunity to discuss some specific feature requirements I currently have with @janine . Thank you again for nudging me in the right direction :slight_smile: . Since returning, I have start…

While I have by now implemented CesiumCartographicGeoJsonPolygon, I am still looking for feedback on the Support for Holes part :stuck_out_tongue:. Added CesiumCartographicGeoJsonPolygon committed 11:07PM - 16 Jun 26 UTC (UTC) …

Hi @hv_nico , It was great to meet you at DevCon! Thanks for posting on the community forum :smile: For reference, I’m sharing the approach we did in Unreal. We added a function that takes an array of points and constructs the spline from it; in this way, you can take the points of a GeoJSON polygo…

Thanks for your reply, @janine ! While I think the ability to convert to Spline Points is great for further fine-tuning, it also introduces some unnecessary overhead to the application. Also, in my opinion, modifying the loaded GeoJSON somewhat defeats its purpose in a geospatial workflow. At that p…

Hi @hv_nico , I appreciate your thoughts on this! Let me take a step back, because I’m worried we’ll go too narrow with implementation details. Currently, Cesium for Unity provides two existing overlays that can handle polygons: CesiumPolygonRasterOverlay, which consumes the CesiumCartographicPol…

You are absolutely right @janine . However, when using a CesiumGeoJsonDocumentRasterOverlay with “Clipping”, this comes with the huge downside that this is purely styling. From my original post: However, this only hides the mesh by discarding the texture during rendering. The mesh itself and its …

@janine Sorry to ping you again. Do you have input towards my last post :grinning_face_with_smiling_eyes:? I would love to open a PR with an implementation once we have agreed on the best methodology :slight_smile: !

Hi @hv_nico , really sorry for the delayed response on this! Since CesiumGeoJsonDocumentRasterOverlay’s use case seem to be purely styling, I don’t know if it would be the correct choice to add RasterizedPolygonsTileExclude to it. You’re right! It wouldn’t make sense, sorry that my response impli…

Hey @janine ! Thanks for your reply - and no worries! With my new implementation, everything already happens at design time, with the option, to also create at runtime. However, I totally also see how adding an Enum to CesiumCartoraphicPolygonwould be a great way to go, to avoid clutter! I don’t …

[image] hv_nico: I noticed that pressing “Troubleshoot Token” on CesiumGeoJsonDocumentRasterOverlayis broken at the moment. I would push a fix for this in the same PR, unless you would like a separate one for that :slight_smile:? Thanks for the catch @hv_nico ! Could you do a separate PR for …

Thanks for the catch @hv_nico! Could you do a separate PR for the bugfix? We’d really appreciate it!
