WoW Model Viewer
WoW Model Viewer is a program that allows users to see all the models for characters, armor, weapons, monsters, and spell graphics in the game files. Additionally, it enables people to take screenshots, add backgrounds, and add weapons/armor to a character of one's choice.
The project was originally created by Ufo_Z and Darjk, who left the source code for developers to build upon and update should the need arise. It continues to be updated.
WMVs are widely used by machinimists with the "blue- (or green-)screen-effect", because there are less limits there than in the real game.
