Whether the face has certain types of edits (not necessarily local - could apply to a subface)

@brief Return true if successfully initialized

Set the parent pointer

------------------------------------------------------------------------------

------------------------------------------------------------------------------

Returns a pointer to the Hbr halfege of index 'idx'

\brief Return the sharpness assigned a given edge

Return vertex ID

Inline methods for accessing vertex and edge sharpness:

@brief Return if the Surface is a single regular patch

Avoid repeated integer modulo N operations:

Simple accessors:

Returns bitmask indicating whether a given facevarying datum for the edge is infinitely sharp. Each datum has two bits, and if those two bits are set

Creasing queries dependent on sharpness values:

Download and extract the archive file at given URL to the source directory specified in the context. dontExtract may be a sequence of path pr

\brief Access the face-varying values associated with a particular face

Returns the id of the face to which this data is bound

@brief Returns the type of parameterization assigned

\brief Get vertex boundary interpolation rule

Weight adjustments to account for phantom end points:

Tag the vertex as being extraordinary

Set the ptex index of the face

Access/modify the values associated with each face:

------------------------------------------------------------------------------ returns the number of edges in a patch with 'numCVs'

Child-to-parent relationships
