The plugin is called 3D FlipBook, for sure, it can perform page flipping animation.
But this is very common ability so all typical plugins are able to do it. 3D FlipBookallows to customize the shape of flipping pages but it is still not enough to be unique.
The main feature is using specially designed physics engine that perform all interaction with a user. This engine is based on physics laws so all user actions with the model seems realistic. The plugin allow you drag and throw pages together. The engine solve the collisions and show natural scene.
Physics engine has a lot of properties: gravity, mass, flexibility, page flipping velocities and much more. But it is little necessary to know for using the plugin because all those properties have default presets.
