Hello, I am the author. This is a reference implementation of
automatic UV mapping using Harmonic Mapping. Because the existing
literature on this topic is so hard to understand, it took me quite a
while to figure out how to implement this. Because of that, I thought I'd
publish a reference implementation of this technique, so that other
who want to do automatic UV mapping don't have to go through all the
pain that I did. To my knowledge, this is the first readable reference
implementation of Harmonic Mapping. If you search quite a bit, you can
find other implementations of Harmonic Mapping, but they are messy,
poorly commented, and hard to understand. In difference to these, my
implementation aims to be readable, and easy to integrate into other
projects. Hopefully, I have achieved this goal.
But unfortunately, if you try and read the source code of my
implementation, you may find that it is hard to understand why it
actually works. Unless you grasp the underlying mathematics, it is
probably difficult to understand the code. That is why I am currently
working on writing an article that explains the underlying
mathematics. I shall publish that article here once it is done. Until
then, please be patient.
