a821 [1] filed a deletion request for insight3d [2]: Orphan and broken for long time (last update in 2015). The sources have been moved here [0] and it misses a dependency (libcl).
It seems that attempts to revive the package have been unsuccessful (last comment from last year reports it fails to build). I think this can be deleted.
