Strange visual artefacts on ViewShed

AndrewWilcockson — Wed, 27 Jul 2022 01:04:46 GMT

Using ArcGISRuntime.WPF version 100.12.0, and .net 8 C# application.

I have a LocationViewShed that I am adding to an overlay on my SceneView, and whilst it is "working" there are weird banding artefacts in the resulting graphics. Note that I see similar weird graphical artefacts in the "Viewshed for Camera" sample application.

Looking at the image you can see the banding I am talking about, and as the viewpoint shifts (analysis remains the same) the colour bands move within the viewshed results.

What layers and elevation surface(s) do you have in your Scene?

I have multiple GraphicsOverlays holding a mix of static and dynamic Graphics.

I have the single AnalysisOverlay holding the LocationViewShed

Elevation data come from DTED loaded through a RasterElevationSource added to SceneView.Scene.BaseSurface.ElevationSources
