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 workaround actually caused linking errors related on missing
symbols and removing the workaround does not cause any duplicated
symbols with MSVC 2013.
In one case, we were comparing int and unsigned int.
In primvarRefiner, some values were safely uninitialized, but older compilers
(GCC 4.1) were complaining.
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.
If the input cv stencil is given and it includes the local point
stencils for endcaps, LimitStencilTableFactory::Create failed
because of incorrect sanity checking.
Although valence 2 gregory patch is not well supported yet, this fix
mitigates artifacts around such a vertex.
Adding a shape catmark_gregory_test8 to see this issue.
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.
- moved TopologyRefiner out of the RefinerFactoryBase into Far
- moved implementation of its Factory<MESH> to far/topologyDescriptor.*
- updated examples and tutorials (no more references to FactoryBase)
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.
