PatchTablesFactory fills 20 indices topology into patchtable, and use it for eval and draw.
note: currently screen-space adaptive tessellation of gregory basis patches is
broken and cracks appear around them.
- new Options for Refine() methods for base face and vertex ordering
- removed ignored/unused "full topology" choice from AdaptiveOptions
- added base face and vertex ordering logic to Refinement
- addition of TopologyRefiner members for component counts and max valence
- refactoring of Level additions to update all new member totals
- addition of GetMaxValence() to TopologyRefiner
- updated PatchTablesFactory to user new GetMaxValence() method
- renaming of "Hole" methods for TopologyRefiner and Vtr::Level
When two instances of TBB were present, the system installed version would take
precedence over an explicitly specified TBB_LOCATION path. This change puts
TBB_LOCATION into the HINTS section and leaves the system paths in the PATHS
section.
When CLEW is present, CL functions become macros which may resolve to null
function pointers. A previous change attempted to guard against CL-related
crashes, but introduced compiler warnings.
This change conditionally tests the function when CLEW is present.
Resolves: #400
- updated original FVar inspection to deal witn non-manifold vertices
- updated FVar refinement to handle > 2 faces per edge
- couple of fixes to use parent topology when child not present
level before we do any further population from the parent as that may
further modify the child's _maxEdgeFaces. When _maxEdgeFaces is incorrect
we may end up with stack corruption problems when
Far::TopologyRefiner::interpolateChildVertsFromEdges() goes to use this data
to allocate some stack space.
- CPU, CPUGL backends both updated
- CL backend still needs work
- Loop subdivision tests disabled because they don't work
- Hedit tests disbaled because they don't work
- regular patches now generated for faces with non-manifold vertices
- non-manifold features treated as boundary edges and vertices
- other minor cleanup/improvement in patch identification method
- commented on approx of smooth x-ordinary corner with regular sharp patch
- added edge-face local-indices to Vtr::Level members
- added internal and public access to edge-face local-indices
- updated refinement methods to use and populate edge-face local-indices
- updated refinement methods to be sensitive to degenerate edges
- added Vtr::VALENCE_LIMIT constant for internal use
- updated Vtr::Level topology completion to fail on valence overflow

- changed return type of Vtr array empty() to bool
- renamed and adjusted arguments to Vtr gather methods for consistency
- removed lone Vtr gather method that took an explicit offset
- updated usage of revised Vtr gather methods in Far
- fixed warnings redeclaring names of local variables already in use
- extend Far::PatchTables data structures & interfaces to store requisite
information for channels of face-varying bi-cubic patches
- implement gather function in Far::PatchTablesFactory to populate face-varying
channels with adaptive patches
- extend accessor interface in Vtr::Level
- propagate code fall-out throughout OpenSubdiv code base, examples & tutorials
- extend vtrViewer code to visualize tessellated bi-cubic face-varying patches
- added new tag for sharp corner, now used in isolation
- split single semi-sharp tag in two for vertex and edge sharpness
- updated tag propagation and all tests of previous semi-sharp tag
- added clear() methods for all tags and simplified initialization
