Either you never had art class in high school, or you forgot that it does not get explained that nicely. Most kids, as well as adults taking casual courses, will never learn this.

Can we go "hey we can fix all of this with a switch in function"? Absolutely. Should I ammend the article with that? Yeah, also absolutely. Is it how the vast majority of people get taught three point perspective? Very much not.

Again, please file an issue so that I don't forget to write that section, because pages on the internet well outlast their life on hackernews, but I work on a million projects and will forget about this if there's no issue =)
