Meshy (formely wxOgreMeshViewer) is a simple, powerful, easy to use mesh viewer for OGRE 3D mesh format. Features skeleton view, animation preview, detailed mesh information, resources.cfg loading for power users, dockable windows, and more
I'm using Ogre for a small student project. This program permit to just open a .mesh file to see it's content and various information about it, including the animations it can perform. This is super useful!
