I briefly walked through the article and I can confidently say these techniques are well-known among graphics programmers. These days even artists who can't write code know what triplaner mapping and PBR are, even though they can't implement them from scratch. Doing something "well" is subjective, but there is no chance there are only less than 1000 people who know these. I'm still thankful to the author for writing these down, of course.
