Because our plugin sets UVs with individual face-varying vertices,
Maya interprets the buffer as discontinuous everywhere. Adding a
node in the graph that merges UVs along non-boundary edges resolves
this problem (until the plugin outputs the UV vertex indices in
an aggregated manner).
The previous fix pointed far indexing tables to the origin vertex
of duped singular verts.
This fix goes one step further and actually shifts all vertex indexing
to start at the end of the coarse mesh vertices, using the space for
data that was previously occupied by duplicated singular verts.
The consequence is that client code no longer needs to duplicate vertex
data in vertex buffers (huzzah !).
- fix FarSubdivisionTablesFactory to shift factory vertex table offsets using Hbr's
singular verts map
- fix schema table factories (Catmark, Loop...) to correctly use these offsets
- remove vertex data duplication code from osdPolySmooth example
- remove some (unrelated) cruft from glViewer example
- shape_utils unfortunately still needs to dubplicate the singular verts to
allow the coarse edge drawing in our example viewers to work correctly
(although it could be fixed to avoid data duplication too...)
fixes#241
- Add a vector of index pairs to HbrMesh to track the index of a split
vertex and its origin vertex
- Correct the Far remap tables in FarSubdivisionTablesFactory to point split
vertices to their origin instead of themselves
- Fix regression/common/shape_utils.h to use the new HbrMesh::GetSplitVertices()
method.
- Fix the osdPolySmooth example to use the new HbrMesh::GetSplitVertices()
method.
- Add a paragraph to the documentation
fixes#241
Also:
- add logic to locate the GUI mel scripts where the binary is located, then default to script search paths
- remove min/max macro defines
- remove iso646.h header (covered by CMake build)
- remove redundant Osd includes
- remove some build warnings
- code style fixes
- build tweak: move the mel scripts to the correct location in the build area
fixes#239
- remove unused variables
- isolate MSVC specific pragmas (these should eventually be cleaned up from the code...)
- add the plugin to the general build
