- added definition to regression/common/shape_utils.h
- removed examples/common/shapeDesc.h and all references to it
- removed local definitions of ShapeDesc from examples, regressions, etc.
- overloaded Shape::parseObj() with ShapeDesc
- updated examples to use Shape::parseObj(ShapeDesc const&);
- removed axis argument to Shape::ParseObj() and ObjAnim::Create()
Read all comments and made corrections to files that aren't part of
OpenSubdiv itself but are packaged with it.
Commandline output of glPtexViewer is affected. Otherwise no functional
changes.
All examples, regression tests and tutorials directly looked into
opensubdiv source directory to grab the header files. This is somewhat
convenient during development but they can mistakenly access private
header files.
With this change, when OPENSUBDIV_INCLUDE_DIR is given to cmake,
it will be used as an include search path to build examples etc.
Otherwise it follows the same behavior as before.
Also replaces include references to the files in regression dir
to be relative, and cleanups some copy-paste patterns.
Sync'ing the 'dev' branch with the 'feature_3.0dev' branch at commit 68c6d11fc36761ae1a5e6cdc3457be16f2e9704a
The branch 'feature_3.0dev' is now locked and preserved for historical purposes.
The Chaikin crease interpolation mode seems to be broken:
- Catmark / Loop / Bilinear are passing the wrong halfedge vertex to the
SubdivideCreaseWeight function which results in sub-edge crease weights
being swapped
- the loop that iterates over adjacent edges needs to check against both
the original edge and its opposite, otherwise it may be incorrectly
accumulated into summation of these adjacent edges (with a 0.25 weight)
The proposed fix:
- Swaps the Dest/Org vertex passed to the SubdivideCreaseWeight (and
we probably want Julian to confirm that this the correct fix)
- Checks against both the original edge and its opposite in the iteration
over adjacent edges
- Replaces the std::vector based query with an HbrHalfedgeOperator for
better performance (hopefully)
The similar fix to OpenSubdiv been reviewed by Tony DeRose.
Also in the fix:
- fix "obj" tag parsing of the smooth triangle tag that was incorrectly
associated with the crease method (and reporting the wrong errors)
- add regression shapes for both Loop & Catmark schemes to hbr_regression
- add same shapes to the glViewer
- improve hbr_regression output to be more readable
- add command-line argument parsing to hbr_regression
- add functionality to dump an obj file when regression fails for comparison

of this quad to be tagged as boundary. These vertices will cause the
feature adaptive pass to generate sub-faces where appropriate, however
the face itself will not be identified as "non-patch", which causes the
FarPatchTables factory to mis-identify it and fall-back on an assert.
This fix flags these particular quad faces in the first adaptive pass.
The particular shape that caused the crash has also been addded to our
regression suite.

Also improved the doxygen target and made the doxy build "quiet".

- [Feature Adaptive GPU Rendering of Catmull-Clark Surfaces](http://research.microsoft.com/en-us/um/people/cloop/tog2012.pdf).
- New API architecture : we are planning to lock on to this new framework as the basis for backward compatibility, which we will enforce from Release 1.0 onward. Subsequent releases of OpenSubdiv should not break client code.
- DirectX 11 support
- and much more...
- generate baseline data with the new hbr_baseline tool
- run the a regression of the current hbr code over the baseline data-set with hbr_regression
There is still some cleanup to do to generalize some of the "shape" code as our intermediate
obj-like file format is unfortunately entrenching itself (we should really be using RIB...)
There is also a fair amounto f copy/pasted stuff in the regression code that needs to be refactored
Closes#32
