be used as intended to specify an installation directory, which can be located anywhere on the
file system.
Also improved the doxygen target and made the doxy build "quiet".
fixes#154
- add tag parsing for h-hole in shape_utils
- re-create Renderman's test shape from the documentation (catmark_square_hedit.h)
- fix Hbr to correctly pass the hole tag from parent to child face
- fix FarSubdivisionTables to handle disconnected face-vertices without crashing
fixes#75
while retaining a necessary 1-ring on the inside of a hole edge
- add IsInsideHole() function to HbrHalfEdge
- add HasChild() function to HbrVertex and HbrHalfedge
- add a regression shape with adjacent holes and creases (tests dart, crease & boundaries)
Note : this does not address hierarchical edits inside holes or hole tags in hierarchical edits
fixes#78
- make sure HBR passes down the hole tag to children when subdividing faces
- minor API modification : allow to unset the hole flag on a face
- modify uniform / adaptive FarMeshFactory to be aware of the flag
- make the FarSubdivisionTableFactory assert when finding unconnected HBR vertices (as it should)
* Uniform subdivision :
The refinement scheme only creates faces & vertices necessary
to maintain the one-ring around the edges of a hole, so this solution
is quite efficient.
* Adaptive subdivision :
At the moment we are still performing full topological analysis on holes and
only skipping patches associated to holes. This is sub-optimal in 2 ways :
1. the topological analysis can potentially be cranking on a lot of unnecessary
geometry
2. even though we may not be drawing the patches, the compute stage is still
applying kernels on all the control vertices of these patches.
We will have to revisit feature adaptive subdivision & holes, so keep the issue active.
fixes#78
- still need to change these changes with other compilers (MSVC / clang...)
- had to add a -Wno-invalid-offsetof for GCC (still need to test w/ other compilers) : apparently gcc 4.4 is somewhat incorrect in tagging our templated class as POD.
- had to change fvarData.h to initialize bitfields to 0 as gcc generates truncated int warnings when trying to initialize 31 bits to -1
- in mesh.h replaced original tbb::concurrent_vector with std::vector until a better solution can be found
Fixes#93
- [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...
output iterators instead of std::vector - eases prman integration
for cases where std::list makes more sense.
Block allocate face children array in common case (<= 4 children).
Other, minor consistency edits.
mutex class with Lock / Unlock public functions.
- remove Mutex implementation from Hbr (and revert to original PRman code)
- provide a Mutex class stub in osd
- add some forward declarations in OsdMesh to limit some of the mutex spills
- #include <osd/mutex.h> where needed (little hackish until we can refactor
some of far better)
- remove ILM_BASE from some CMakeLists
Closes#48
