| # PMX 2.0 file format # | |
| This is a description of the PMX file format. This is used for 3D models in Miku Miku Dance (MMD). | |
| Since I couldn't find any English descriptions of the PMX file format, I've made this, which is translated from http://gulshan-i-raz.geo.jp/labs/2012/10/17/pmx-format1/. I haven't used this file format yet, so please don't ask me what everything means. | |
| An English guide to the PMD file format, which preceeded PMX, can be found here: http://mikumikudance.wikia.com/wiki/MMD:Polygon_Model_Data. | |
| If you want to learn more, there are some open source projects on GitHub which can read this format, so go take a look at them. | |
| Note: fields with type text begins with an int (32 bit) with how many bytes of text the section is. |

What is strict aliasing? First we will describe what is aliasing and then we can learn what being strict about it means.
In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.
Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we th
