Custom RGB PNG Terrain via GeoServer – Low FPS in Cesium

[Luke_McKinstry]

Hi @ugur_ince,

Thanks for your post and welcome to the Cesium community.

1. Cesium handles tile loading based on the camera view. You can see this in action using this sandcastle Cesium Sandcastle which uses the viewerCesiumInspectorMixin.

2 & 3.

• Here are some past conversations regarding heightmap custom terrain providers which might be useful
  • Understanding Cesium heightmap terrain data
  • Custom terrain server questions
• You can check bandwidth by setting your browser to simulate low latency
• If you can change the tile size you are serving, the CustomHeightmapTerrainProvider class let’s you specify the input tile width and height CustomHeightmapTerrainProvider - Cesium Documentation

Hopefully these tips can help you make progress. Feel free to ask further questions as you narrow down your bottle neck and improve performance, and please let us know what you find and what works to speed up your custom terrain setup!

Thanks,
Luke
