Instantiates a PatchTable from a client-provided TopologyRefiner.

A PatchTable can be constructed from a TopologyRefiner that has been either adaptively or uniformly refined. In both cases, the resulting patches reference vertices in the various refined levels by index, and those indices accumulate with the levels in different ways.

For adaptively refined patches, patches are defined at different levels, including the base level, so the indices of patch vertices include vertices from all levels. A sparse set of patches can be created by restricting the patches generated to those descending from a given set of faces at the base level. This sparse set of base faces is expected to be a subset of the faces that were adaptively refined in the given TopologyRefiner, otherwise results are undefined.

For uniformly refined patches, all patches are completely defined within the last level. There is often no use for intermediate levels and they can usually be ignored. Indices of patch vertices might therefore be expected to be defined solely within the last level. While this is true for face-varying patches, for historical reasons it is not the case for vertex and varying patches. Indices for vertex and varying patches include the base level in addition to the last level while indices for face-varying patches include only the last level.
