 ### To Do
-- rotation problem
+- center and normalize
-- cloth not working correctly
+- open file while runtime does not work
+- drag and drop does not work
+- tga with alpha cannot be opened
+- multi polygons not correctly triangulated
+- 5+ polygons => corrupted file
 - optional display bones, shadow, collision,...
 - integrate into a software:
--> gui open file ( + drag and drop),
 -> list all msh under a directory,
 -> display shadows,
 -> display colisions,
