TaiChi: Open-source computer graphics library

For anyone interested - since its not immediately clear from the website (though the graphics are stunning) – TaiChi is a cross platform combined physically based animation and physically based rendering toolkit/ library. It wraps a lot of current state of art research algorithms and significantly simplifies doing graphics R&D. It is also a lot of fun to play with.

With a basic background in computer graphics, I found it took me about 4-6 months to understand and implement a paper like APIC from scratch. TaiChi's author, Yuanming Hu, apparently implemented that and 9 other papers in the same time. It probably helped a lot that he worked directly with the paper authors, but he certainly has been very productive.

I really appreciate that somebody is implementing these papers in the open. It's incredibly useful to have a reference implementation available to study alongside the paper. Seeing the same thing in a few different ways is great for learning.

His 88-line implementation of MLS-MPM is probably a little too much like code-golf, but when I expanded it out to 188 lines, I found it really enlightening.

So it's not doing physics?

I believe it is doing physics. See http://taichi.graphics/gallery/ for some examples.

It is both not doing and doing physics. That is the TaiChi way.

Actually, the TaiChi way would be "not-doing" (Wei Wu) physics. See: http://www.the-taoism-for-modern-world.com/wei-wu-wei-not-do...

It's the other way around, wu wei--the absence of effort. The extra wei in the front is the "doing" of "not doing" (wu wei) which seems to be something particular to this author. https://en.wikipedia.org/wiki/Wu_wei
