shorten code,

tested multipoly, there are some problems, look at the README.md,

 ### To Do
-- cluster seam to use wrong textures
+- cluster use wrong textures
-- multipoly testing
+- use normals or fix ccw and cw
+- multipoly triangulation not 100% good
 - cloth testing
 - optional display bones, shadow, collision,...
 - integrate into a software:
