- converted classes for stencils, tables and factories to templates

- extended PatchTable to support variable precision stencil tables
- extended PatchTableBuilder to manage PatchTable's new stencil tables
- templated PatchTableBuilder conversion from SparseMatrix to stencils
- extended public PatchTableFactory interface to specify precision
- converted PrimvarRefiner class to template and added wrapper class
The methods which return arrays of FVarPatchParam have
been made plural, e.g. GetFVarPatchParams(), for consistency
with the other methods in PatchTable.
Also fixed a missing doxygen tag.
This reverts most of the recent changes to the
organization of Far::PatchParam. In particular,
the core parameterization is no longer exposed
as a speparate PatchParamBase class.
We'll revisit this again in a later release, but
for now we will stick with a more straight
forward implementation.
The patches generated for a face-varying channel can be a
mix of regular patches and patches in an alternate basis
for faces that are irregular in face-varying space.
This mix of patches is packed into a single fvar value array
in the patch table using a consistent stride with the individual
patch type determined by the fvar patch param encoding.
- Added Far::PatchParamBase::IsRegular() to designate which
patches are regular.
- Updated Far::PatchTableFactory to gather mixed basis
patches when using the Gregory basis approximation for
irregular patches.
- Fixed Far::PatchTable::EvaluateBasisFaceVarying() to
use the fvar patch param encoding to determine the type
of face-varying patches.
Updated Far::PatchTableFactory to be able to populate patches
for smooth evaluation of face-varying data channels.
- Moved computePatchTag() method to BuilderContext
- Added computeFVarPatchTag() method to BuilderContext
- Use Vtr::Level::VSpan to represent the partial ring
around vertices for face-varying patches.
- Added the option generateFVarLinearPatches (defaults
to true) to support the legacy behavior of generating
linear patches for face-varying data channels regardless
of the underlying face-varying linear interpolation modes.
These methods now compute the patch basis in terms
of Far::PatchParamBase instead of Far::PatchParam
This allows these methods to be more easily reused
for evaluating patches for face-varying data.
In order to support a consistent API for refinement and
evaluation of varying primvar data, Far::PatchTable needs
to provide indices for varying data. This adds support to
Far::PatchTableFactory for generating these indices.
This change updates Far::PatchTable to include support for
evaluating varying and face-varying data on patches.
This adds to existing API and follows the existing patterns
used for vertex patches.
This includes data and methods to evaluate varying and
face-varying basis functions as well as methods to compute
local point values for varying and face-varying primvar data.
This is the foundation for updating Far::PatchTableFactory
to generate bicubic patches for face-varying channels.
This change restores the use of 4-bits in Far::PatchParam to
encode the refinement level of a patch. This restores one bit
that was stolen to allow for more general encoding of boundary
edge and transition edge masks. In order to accommodate all
of the bits that are required, the transition edge mask bits
are now stored along with the faceId bits.
Also, accessors are now exposed directly as members of Far::PatchParam
and the internal bitfield class is no longer directly exposed.
We'll restore this code and finish it up for the next release.
For now, removing this code restores parity with the 3.0 beta,
i.e. face-varying patches are always all bilinear.
There's a lot of good foundational work here to eventually support
smooth interpolation of face-varying patches. Unfortunately, this
is not quite ready to release. Therefore, we've decided to defer this
feature until a later release.
This change hides this code behind the FAR_FVAR_SMOOTH_PATCH macro.
Now the channel specifier is the last parameter in a method's
parameter list with a default of 0. This is consistent with the
topological face-varying queries and also simplifies the common
case of just a single face-varying channel.
To encapsulate endcap functions from public API, add methods to
tell the number of patch points needed (GetNumLocalPoints()) and
to compute those patch points as a result of change of basis from
the refined vertices (ComputeLocalPointValues()).
ComputeLocalPointValues takes contiguous source data of all levels
including level0 control vertices.
