To achieve this, OpenSubdiv 3.0 introduces many improvements that constitute
a fairly radical departure from previous versions.
This document highlights some of the major changes that have gone in to the 3.0
release.

Sdc provides the low-level nuts and bolts to provide a subdivision

Far layers but may also able to provide an existing client's implementation
with the details necessary to make that implementation consistent with
OpenSubdiv (though not without considerably more understanding and effort).

Topology and Refinement
***********************
Given repeated limitations experienced with Hbr as the primary topological
entry point, OpenSubdiv 3.0 introduces a new *intermediate* internal
topological representation named **Vtr** (Vectorized Topology Representation).
Vtr is much more efficient for the kinds of topological analysis required by
Far and additionally is more flexible. As a result, Hbr is no longer a core
API of OpenSubdiv. While the code is marked as deprecated, it will remain in

Compared to the Hbr library used in previous versions, Vtr is much more

the source distribution for legacy and regression purposes.
