Noticed a few typos when browsing comments. Proceeded with a "manual
spell check", reading all comments and tweaking spelling, grammar,
punctuation.
Didn't bother with Hbr library.
Comments only, no functional changes.
- extended smooth corner patch approximation to fvar and inf-sharp patches
- fixed assignment and refinement bugs for inf-sharp tags in fvar space
- fixed interpolation bug with Bilinear scheme and LINEAR_NONE option
- added public methods for fvar topology to Far::TopologyRefiner
- updated face-varying VTag conversion to set VTag::_corner correctly
- updated adaptive refinement to prevent over-isolation of inf-sharp features
- fixed patch regularity test when inf-sharp and xord features not separated
at level 0 or 1
- generalized BSpline end-cap factory boundary test to defer to Gregory patch
for any non-smooth corner
- changed Level::VSpan start member from edge to face local index
- added additional Level::VSpan members for non-manifold cases
- updated existing usage of Level::VSpan for new members and methods

- added tags for inf-sharp features to Vtr::FVarLevel::ValueTag
- updated the conversion from ValueTag to VTag
- removed awkward and little used tagging methods from Vtr::FVarLevel
- replaced obsolete methods in face-varying adaptive refinement
- changes mainly involve Far::PatchTableFactory
- treatment of patches more clearly separated into regular and irregular
- patch identification now determines regularity and defers classification
- topology inspection specialized for regular vs irregular patches
- face-verying patches re-use patch information when topology matches
- added Vtr::Level methods to improve access to tags for face-varying values
- improved initial tagging of face-varying values in Vtr::FVarLevel
- added new Vtr::Level::VTag members for inf-sharp features
- updated Vtr::Level::print() to recognize new tags
- explicitly initialized tags for new edge-verts in Vtr::Refinement
- initialized tags for base level verts in Far::TopologyRefinerFactory
- added definition and gathering method to Vtr::Level
- extended Far::EndCap...PatchFactories with VSpan[4] for patch corners
- extended Far::EndCapGregoryPatchFactory to avoid last level assumption
- adapted Far::PatchTableFactory to use above extensions
- extended Far::GregoryBasis to recognize VSpan corners
- simplified Far::GregoryBasis treatement of boundaries
- fixed bug in Far::GregoryBasis related to smooth corners
This fixes a regression in the function used to identify single crease
patches. This also updates the patch color values used by the glImaging
regression test to match the colors used in other example viewers so
that patch types can be more easily identified during automated testing.
- 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
- correctly initialize FVar tag and source entry for unconnected verts
- added regression/shape with unconnected vertices and fvar data
- fixed edge-face vector access when unconnected edges are last
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)
- change public status of members back to protected/private
- mimized friends (primarily Refinements as builders for Levels)
- added any missing accessors to prevent member access (mainly Tags)
- added the Tri/Quad refinement subclasses to private header list
- updated PrimvarRefiner to make use of now-local Mask class
- renamed vtr/maskInterfaces.h to vtr/componentInterfaces.h
- updated usage of renamed header file and CMakeLists.txt
- removed TopologyRefiner options to propagate base face in Refinememt
- removed all Vtr storage and management of base face
- added PrimvarRefiner methods to "interpolate" per-face primvar data
- removed all friend declarations (no more Far declarations with Vtr)
- all protected methods made public
- intent is to move these into namespace internal
- access between Vtr classes is under review
- changed Vtr::LocalIndex to 16-bit integer from 8-bit
- added test shapes including valence 360 vertices
- disabled new shapes in far/regression until improved accuracy accepted
While this may be worth revisiting, we should first quantify the benefits and
identify the compilers that support it. Ultimately, we may never use pragma
once in favor of strictly using standard C++.
- removed default value for its <SIZE> parameter
- updated all usage to specify a value for <SIZE>
- added explicit element destruction missing from destructor
- corrected comment regarding VLA's being non-standard
The previous change to the gathering of patch points went
a bit too far. Near non-manifold features it is important
to be careful when traversing the faces in a level to avoid
assumptions that are valid only for manifold topology.
Also, removed Vtr::Level::gatherQuadRegularPatchPoints().
This method was added in my previous change, but it is
unsafe to use in the presence of non-manifold topology.
