@Rion Thanks for the Feedback...
But as this was a rushed release, because of me trying to be helpfull, it has taken me a while to come up with the next step...

The VPCalc script itself was ready in the time I opened this topic, but me and readmes are only friends in context of me reading them, not writing such.... (and then, in (CP)2020 CP2077 came to be)... well, as life is passing by, instead of having the filter scripted and at least in beta stage by now, I may have that one ready in 202101/02 ... here we are with the viewport calculator: Project VPC: VPCalc at least. ...

As I had to use used some markdown/html patchwork to create the readme which is, so far and for now, working on git, but unusable here.... I am only providing the link for now...

Edit: And a look at the UI:
VPCalc-UI

Besides me living in Night City at the moment, the UI for the filtering App/Script is in its alpha and ready to be populated/used by/with further scripting.... sneak preview:
