Issue description
When there are more than 100 POIs, some will not display in the 2D Map view even when zoomed in/out, visibility check on/off. But in Panorama view/Point cloud view, the POIs there are visible.
The reason for this is there is only so much space on the map view, and trying to show 10,000 POIs on the map is not possible in a meaningful way. It's a tradeoff for performance that we do not download all POIs for a floor and then filter out all but a few on the frontend. So we only request a reasonably low amount (like 100), sorted by POI importance, and then apply the screen-space overlap test.
Troubleshooting procedure
Set importance to higher level (we sort by importance for map).
In the map view, you can see the 2D maps of the site and where the site is located on a world map. By default, the map view is displayed in the mini view, which is the small window in the bottom right corner of the NavVis IVION interface. Clicking on the two small arrows on the bottom right corner of the screen switches between panorama view and map view.
In the panorama view, you can explore your data in a seamless experience. In this view, you can see both panoramic images and point clouds. By default, the main view of the NavVis IVION interface shows the panorama view.
A three-dimensional representation of an environment, made up of many points. A point is defined by x, y and z coordinates, and it may or may not contain RGB, an intensity value, and normals.
