Catmull-Clark Subdivision Surfaces", Niessner et al, Eurographics 2012.
This change includes;
-topology identification for single-crease patch during adaptive refinement.
-patch array population (similar to boundary)
-sharpness buffer generation
-glsl shader
Eval stuffs will be coming.
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.
- remove obsolete glPushClient functions
note: this code is still duplicated in the ptexViewer (which still needs to be upgraded to the new framebuffer)
fixes#307
If the system has CLEW installed (which is detected by recently
added FindCLEW routines) then OpenSubduv would be compiled against
this library.
It makes binaries and libraries more portable across the systems,
so it's possible to run the same binary on systems with and without
OpenCL SDK installed.
The most annoying part of the change is updating examples to load
OpenCL libraries, but ideally code around controllers and interface
creation is to be de-duplicated anyway.
Based on the pull request #303 from Martijn Berger
- Some missing includes of <algorithms> in order to have
stdd::min() and similar functions.
- Need to cast numIndices and numNVerts to int explicitly
in order to solve warning treated as an error about
precision loss.
- Can't do vector[0] for an empty vector, it'll generate
a runtime range check error.
- MSVC only works fine with make_pair(foo, bar) syntax,
without explicit template substitution here. Otherwise
weird 'can't cast int to int&&' errors are happening.
- add a framebuffer to gl_hud with programmable image shader
- add optional SSAO image shader to the new framebuffer
- add screenshot to png functionality
- implement in glViewer
note: ptexViewer and some others still need refactoring to use the new hud capabilities
- fix default selection for pulldown widgets
- move widgets around to prevent overlap in examples
- add a little triangle indicator to the pulldown widget
- switch color from white to yellow for selected pulldown item
On platforms with multiple devices (e.g. OS X Mavericks
with both Intel and Discrete GPU CL devices) we must
create the context and command queue with the correct
device in order to share resources with GL.
This follows existing patterns (more or less), but
there are certainly opportunities to move more of this
sort of logic into macros defined at the top level.

- Adding FarStencilTables and FarStencilTablesFactory classes
- Adding Osd EvalStencil context & controllers for CPU, OMP and TBB backends
- Adding the code example glStencilViewer
- Adding reST documentation
- Changing version to 2.2.0_dev
- Fix HbrMesh::Unrefine function
- Fix "CanEval" function in OsdVertexBufferDescriptor
Note 0: there is no stencil support for hierarchical edits
Note 1: there is no support for face-varying data stencils yet
Note 2: the current stencil factory is lazy but the caching system is not re-entrant
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector
Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)
In example code, GLUT has been replaced with GLFW so that glViewer/ptexViewer can run on OSX (10.7 or later).
OSX note: still have some problem with clang, may need to explicitly specify gcc on cmake cmdline
-DCMAKE_CXX_COMPILE=/usr/bin/g++
fixes#98
- consolidate cmake compile flags
- turn on -Wall
- suppress hidden overloaded function warning when using Clang
(part of it is bug, part of it will require code refactoring
on our end)
- add support for Maya 2013.5 for windows in cmake module
- clean up some glew includes which break builds with MSVC Express
& Windows SDK
- move the bitmap for font_image into a compiled object
- remove some unused variables and other minor warnings
Note : this is a checkpoint, there are still a few more warnings to clean up...
fixes#96
- [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...
