- instead of accumulating GregoryBasis::Point (fixed size stencils
backed by stackbuffer), pack the stencils into StencilTable as they
are evaluated
- use single integer for varying stencils of patch points, not
a GregoryBasis::Point
- cap the reserved stencil entry size.
generateAllLevels flags is used when we want to have uniform refined
patch array containing all levels together. There's an index offsetting
bug when this flag is enabled.
- eliminated need for disabling warning 177 in far/patchTableFactory.cpp
- encapsulated all floating point equality tests (1572) in local functions
- bracketed all ICC specific warning pragmas with #ifdef __INTEL_COMPILER
- avoided GCC's stricter shadowing warning in vtr/array.h
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.
stb - potential use of uninitialized variable (this may have been safe)
farViewer - unused variable
patchTableFactory - _channelIndices potentially used uninitialized
FVarLevel - valueIndexInFace0 potentially used used uninitialized (was safe)
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.
use boundaryMask to identify the crease edge from 4 edges.
with this change, single-crease patch no longer needs to be rotated on
its population.
In shader, experimentally use same infinite sharp matrix for both
boundary and single-crease patch.
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.
