Cluster points with tilted camera (calculate cluster in screenspace?)

[pcace]

Hi there,

i am using supercluster for houndreds of points with success.
the issue i am having is, that the clustering works great when looking at the map from the top, when tilting the camera more to the horizon it is not really working anymore, since it does (as far as i understand) uses bbox + zoom.
so when in a high zoom level and tilted camera to the horizon elemens are not clustered anymore.

any idea what i could do here?

in this example the items on the horizon should be clustered.
