Note the bit-mask here is specific for use with Far::PatchParam

High-level queries related to the subdivision scheme of the refiner, the patch types associated with it and those chosen to represent its faces:

\brief Returns the subdivision options

\brief Returns the size of the stencil

interfaces needed for D3D11ComputeEvaluator

Class methods supporting access to patches:

\brief Returns the transition edge encoding for the patch.

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

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

\brief Access the edges incident a given vertex

\brief Access the faces incident a given vertex

Return width of the data

Returns the active developer directory as reported by 'xcode-select -p'. Returns None if none is set.

More than one FVar surface may be present, and each may have a unique ID:

Increment the usage counter on the vertex

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

Simple get/set methods to avoid the tedious syntax of the tag:

\brief Return if the edge is non-manifold

@brief Return if the Surface is linear

Returns whether the edge is sharp at the current level of subdivision (next = false) or at the next level of subdivision (next = true).

Returns whether the vertex is singular (has two separate incident halfedge cycles)

\brief Return if the vertex is on a boundary (at least one incident boundary edge)

\brief Return if the vertex is non-manifold

Create new face children block for use by HbrFace

"Create" a new uniform index

\brief Advance to the next stencil in the table

Higher level basis evaluation functions that deal with parameterization and boundary issues (reflected in PatchParam) for all patch types:
