The OpenSubdiv public interface currently requires only C++11 but we
choose this version since C++14 has been the default since GCC 6,
Clang 6, and Visual Studio 2017 (for the most part) and C++14 has been
the default for OpenSubdiv on macOS when support for Metal is enabled.
This setting is guarded so that it can be overridden by the caller when
running CMake.
Fixes#1276
This introduces an internal glLoader library which allows
most of the implementation to be agnostic about the
implementation of the GL loading library. Specifically,
this removes references to the GLEW headers and libraries
from the rest of the source code and build system.
Split the examples/common objects into graphics API dependent object
libraries (following the pattern used for cemmon Ptex dependencies)
so that DX11 and Metal examples are no longer forced to link with GLFW.
Removed the link dependency from libosd to
the Ptex library since Ptex is used only by the
examples. Updated examples/common to separate
the common Ptex sources from the other common
sources so that they are used only by the Ptex
examples.
- updated CMakeLists to account for the moved files
- updated references to argOptions.h in all examples
- added method to ArgOptions to populate vector<ShapeDesc>
- minor changes to ViewerArgUtils to use forward references
- 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()
Started refactoring how we parse arguments for sample viewer
applications into a common place. This will make it easier
to keep args consistent between applications.
- the framebuffer class in examples/common is unstable in certain drivers.
removing offscreen rendering for now.
- move screenshot function to GLUtils.
- fix vertex attrib binding bug (not showing control mesh on osx)
- add GLControlMeshDisplay and D3D11ControlMeshDisplay into
examples/common
- delete all drawCageEdges/drawCageVertices from viewers and
use ControlMeshDisplay class
- Make sure to declare usage of the include files if GLFW is found
- When GLFW is found and is compiled into examples/common, we need to
unfortunately link it into dxViewer. Hopefully we can refactor common
so that this won't be necessary in the future.
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.
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.
Remove DrawRegistry from osd layer and put a simple shader caching
utility into examples/common. osd layer only provides patch shader
snippet and let client configure and compile the code. Clients also
maintain the lifetime of shader object, which is preferable for the
actual application integration.
update all examples to use the new scheme.
we're teasing out ptex specific data from core osd entities,
so there's no reason to keep ptex texturing utilities in core osd.
move them into example libs and let clients assemble shader snippets
as needed.
Also removing older ptex texturing code (without mipmap)
refactor CL/CUDA specific initialization stuffs into
examples/common/clDeviceContext and cudaDeviceContext, and
update examples to use those structs.
also
- remove CL/CUDA tests from osd_regression. The tests for those kernels will be covered by glImaging.
- update cuda initialization to use the GL-interoperable device if available.
- remove CL specialization from glShareTopology, following the same pattern as we took in the previous OsdGLMesh refactoring. (still something strange with XFB kernels though)
- fix file permissions.
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.
- 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
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.
