*
* This loader loads and parses PMD/PMX and VMD binary files
* then creates mesh for Three.js.
*
* PMD/PMX is a model data format and VMD is a motion data format
* used in MMD(Miku Miku Dance).
*
* MMD is a 3D CG animation tool which is popular in Japan.
*
*
* MMD official site
* http://www.geocities.jp/higuchuu4/index_e.htm
*
* PMD, VMD format
* http://blog.goo.ne.jp/torisu_tetosuki/e/209ad341d3ece2b1b4df24abf619d6e4
*
* PMX format
* http://gulshan-i-raz.geo.jp/labs/2012/10/17/pmx-format1/
*
*
* TODO
* - light motion in vmd support.
* - SDEF support.
* - uv/material/bone morphing support.
* - more precise grant skinning support.
* - shadow support.
