very interesting discussion. I don't think applying this to what we have now will make a big change, right now. But who knows, maybe in the future we will move away from simplistic models and use stuff like this. This is just one of many baby steps to take towards more realism - eventually it will all add up.
...you're not breaking anything as a theory. I'm not even sure what you mean by that. Do you mean stating something that people have known for a long time? The kind of thing you can read in almost any book on perspective? 3 point perspective isn't something you "break". It never claims to do the things you point out it…
