Methods comparing to a superset (not any arbitrary subset):

Public methods to retrieved cached Surfaces and their pre-computed patch points:

SourcePatch method to initialize other internal members once required members of all corners have been explicitly initialized. This deals with all of

Virtual method defaults -- intended to be overridden for thread-safety:

Must be called after the edge map has been populated

returns true if a block can fit in this slot

Executes the specified command and returns output or None.

Returns the destination vertex ID

\brief Return the child vertex (in the next level) of a given edge

\brief Access the faces incident a given edge

Returns the edgeVertIndex for a given Hbr halfedge 'e' and vertex 'v'

Return a table of the start index of each facevarying variable

\brief Return the child vertex (in the next level) of a given face

Ask for client data associated with the face with the indicated ID

Return index into the facevarying data

@brief Return the number of boundary coordinates

@brief Return the number of face-varying channels

Access to member variables is preferred through these methods, which may require a little more logic than expected:

Return offset of the data
