Hi @mvoermans,
Cesium is loading all tiles at minimumLevel
at startup.
If you are displaying only a small extent you can define a rectangle and bump this value accordingly.
Maybe that could be implemented with a https://cesium.com/learn/cesiumjs/ref-doc/TileDiscardPolicy.html
Hi @gberaudo,
Thanks for your response!
I think that won't fix my problem. I have an WMS layer with a min and max resolution like in this example: https://openlayers.org/en/latest/examples/min-max-resolution.html When I open this layer in Cesium and I zoom out of the resolution settings, Cesium still send WMS requests.
If I look at the Cesium documentation: https://cesium.com/learn/cesiumjs/ref-doc/WebMapServiceImageryProvider.html#.ConstructorOptions I see there is a minimumLevel and maximumLevel setting.
Is it possible with OLCesium to set this setting for a WMS layer?
Hi @mvoermans, the documentation you points says: """ The minimum level-of-detail supported by the imagery provider. Take care when specifying this that the number of tiles at the minimum level is small, such as four or less. A larger number is likely to result in rendering problems. """
I am not aware of a mechanism similar to OL in Cesium. If you find something please report it here so that we can integrate it.
Some layers are only visible at some levels. Is is possible to set the minimumLevel like olcs.projection as an extra setting.
