Feature Adaptive Representation (Far)
=====================================
Far is a serialized topoloigcal data representation.Far uses hbr to create and
cache fast run time data structures for table driven subdivision of vertices and
cubic patches for limit surface evaluation. `Feature-adaptive <subdivision_surfaces.html#feature-adaptive-subdivision>`__
refinement logic is used to adaptively refine coarse topology near features like
extraordinary vertices and creases in order to make the topology amenable to
cubic patch evaluation. Far is also a generic, templated algorithmic base API
that clients in higher levels instantiate and use by providing an implementation
of a vertex class. It supports these subdivision schemes:
