- resolves DX-CL interop functions in Osd::ClD3D11VertexBuffer.
- enable CL kernels in DX build.
- more cleanup in test harnesses, adding D3D11 initializations into DeviceContext.
- add new defines OPENSUBDIV_HAS_OPENGL and OPENSUBDIV_HAS_DX for convenience.
- removed default value for its <SIZE> parameter
- updated all usage to specify a value for <SIZE>
- added explicit element destruction missing from destructor
- corrected comment regarding VLA's being non-standard
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.
The previous change to the gathering of patch points went
a bit too far. Near non-manifold features it is important
to be careful when traversing the faces in a level to avoid
assumptions that are valid only for manifold topology.
Also, removed Vtr::Level::gatherQuadRegularPatchPoints().
This method was added in my previous change, but it is
unsafe to use in the presence of non-manifold topology.
Removed OpenCL/D3D11 specialization and add DEVICE_CONTEXT as a template
parameter. For the kernels which don't need a context object (e.g.
CPU, OpenGL, cuda) just ignore the context, and for the kernels which
use a context (e.g. OpenCL, DirectX) takes a context or a user-defined
class as which encapsulates device contexts. Note that OpenCL requires
two objects, cl_context and cl_command_queue. The user-defined
class must provide GetContext() and GetCommandQueue() for strongly typed
binding to osd VertexBuffers and ComputeContexts.
Osd::Mesh and MeshInterface have been used as a handy harness to host
multiple GPU kernels and graphics APIs. However it has CL/DirectX
specializations and duplicates large amount of plubming code. With this
change, glMesh.h and d3d11Mesh.h become just typedefs and all logic is
put into mesh.h without specializations.
Also cleaned up unused header files and code formatting.
- Upped minimum required version of docutils from 0.6 to 0.9.
- Fixed link to pygments in build documentation
- Fixed link to doxygen in build documentation
Now a boundary and corner patch remains
aligned with its underlying parametric
orientation. This simplifies both the
gathering of patch vertices and downstream
evaluation of patches.
Added a method to Vtr::Level which gathers
the 16 patch points for a B-spline patch
even if the patch has boundary or corner
edges. The undefined patch vertex index
values along boundary and corner edges are
assigned Vtr::INDEX_INVALID.
In order to simplifiy the process of drawing
B-spline patches with boundary or corner
edges, the Far::PatchTablesFactory will
replace any invalid vertex indices with
a known good value, i.e. the index of the
first patch face vertex.
Single-crease patches are still a slightly
special case, which will be resolved later.
- rename "Regular end cap" to "BSplineBasis end cap"
- revert templating and add EndCapType into PatchTablesFactory::Options.
- make EndCapFactories internal in PatchTablesFactory.
- move end cap stencils into PatchTables, keep them relative to the max level.
- add a utility StencilTablesFactory::AppendEndCapStencilTables to splice and factorize endcap stencil tables.
