Problem in rendering point cloud 3D model and WMS layer imagery

[mwu2018]

If a point cloud 3d model and wms layer are added in the same location, these two items will interfere each other. The results are

• The map might become less responsive.
• The point cloud model appears to be less dense.
• Data loading become very slow or pause.
• Some black stripes might appear on the screen when zooming in/out.

This is due to how cesium loads and renders tiles - it will wait until all data for a given tile has been loaded before rendering.

There might be ways of tweaking it, but I am not sure.

For me, the issue really lies with performance of the underlying web services - if the WMS layer is slow to load, then everything else will be slow. I think it might be better to try to optimise these web services before looking into how Cesium handles network requests and rendering data
