Far::LimitStencilTableFactory computes limit stencils using
patches from a Far::PatchTable, creating one temporarily if
necessary. This change propagates the useInfSharpPatch option
from adaptively refined topologies.
Recent CUDA SDKs no longer support the "compute_11"
gpu architecture. We now fallback to "compute_20"
instead for newer SDK versions. Additionally, this
behavior can be overriden using the new CMake list
variable OSD_CUDA_NVCC_FLAGS so that it is easier
for clients to target newer architectures and specify
additional arguments.
- added new public member to PatchTableFactory::Options
- replaced internal option with new public option
- updated tagging and Gregory conversion for sharp patches
Implemented EvalPatchesVarying and EvalPatchesFaceVarying
methods for Osd::*Evaluator classes, i.e. cpu, omp, tbb,
GLXFB, GLSLCompute, OpenCL, and CUDA.
Also, the GPU Kernel implementations have been updated to use
the common patchBasis implementation instead of re-implementing
methods to compute patch basis weights locally.
This is used to compute patch basis weights for
the Osd::*Evaluator classes that are unable to
use the C++ implementation from far/patchBasis.h,
e.g. the GLSL, HLSL, OpenCL, and CUDA kernels.
Instead of duplicating this code for each different
kernel language, we share a single implementation
which is minimally adapted to accommodate specific
language restrictions and syntax.
This implementation can also be used by client
shader code executed while drawing, e.g. to
compute patch basis weights for evaluating varying
and face-varying patches.
This was an obsolete relic from when PatchDescriptor
was more than a single enum value, but it can cause
problems when sharing patch descriptor values between
devices.
Also, marked the GetNumFVarControlVertices() method as
deprecated.
This reverts most of the recent changes to the
organization of Far::PatchParam. In particular,
the core parameterization is no longer exposed
as a speparate PatchParamBase class.
We'll revisit this again in a later release, but
for now we will stick with a more straight
forward implementation.
This change updates the Far::LimitStencilFactory to
to support options to generate 1st and 2nd derivative
limit stencil weights.
For backward compatibility, the option to generate 1st
derivatives defaults to true. While for efficiency,
the option to generate 2nd derivatives defaults to false.
Also, updated the Far::LimitStencil class to expose
computed 1st and 2nd derivative limit stencil weights.
- added flag to consider features in face-varying channels
- added flag to reduce refinement for infinitely sharp patches
- added secondary isolation level to reduce refinement of smooth features
- updated face-varying VTag conversion to set VTag::_corner correctly
- updated adaptive refinement to prevent over-isolation of inf-sharp features
- fixed patch regularity test when inf-sharp and xord features not separated
at level 0 or 1
- generalized BSpline end-cap factory boundary test to defer to Gregory patch
for any non-smooth corner
