data representation scheme for storing computer graphics scenes
Alembic is a computer graphics interchange framework, developed by Sony Pictures Imageworks and Industrial Light & Magic. It distills complex, animated scenes into a non-procedural, application-independent set of baked geometric results. It is very specifically not concerned with storing portions of the assets such as animation rigs. Instead, Alembic is used to bake things like the geometry and physics of an animated scene, the results of which are then ready for hand-off to lighting and rendering.
