Description: Egg files are used by Panda3D to describe many properties of a scene: simple geometry, including special effects and collision surfaces, characters including skeletons, morphs, and multiple-joint assignments, and character animation tables.

History: Panda3D was developed by Disney for their massively multiplayer online game, Toontown

Example(s): Example Template Many application and file examples exist here.
