This commit adds a worklet as well as a filter that modify point coordinates by moving points
along point normals by the scalar amount times the scalar factor.
It's a simpified version of the vtkWarpScalar class in VTK. Additionally the filter doesn't
modify the point coordinates, but creates a new point coordinates that have been warped.
This commit adds a worklet as well as a filter that modify point coordinates by moving points
along a vector by a certain scalar amount.
It's a simpified version of the vtkWarpVector in VTK.
It doesn't modify the point coordinates, but creates a new point coordinates that have been warped.
The original design of invoke and the transport infrastructure
relied on the implementation behavior of vtkm::cont types
such as ArrayHandle that used an internal shared_ptr to managed
state. This allowed passing by value instead of passing by
non-const ref when needing to transfer information to the device.
As VTK-m adds support for classes that use virtuals the ability
to pass by base pointer type allows for us to invoke worklets
using a base type without the risk of type slicing.
Additional by moving over to a non-const ref Invocation we
can update all transports that have 'output' to now be
by ref and therefore support types that can't be copied while
being 'more' correct.
Most of the arguments given to device adapter algorithms are actually
control-side arguments that get converted to execution objects internally
(usually a `vtkm::cont::ArrayHandle`). However, some of the algorithms,
take an argument that is passed directly to the execution environment, such
as the predicate argument of `Sort`. If the argument is a plain-old-data
(POD) type, which is common enough, then you can just pass the object
straight through. However, if the object has any special elements that have
to be transferred to the execution environment, such as internal arrays,
passing this to the `vtkm::cont::Algorithm` functions becomes
problematic.
To cover this use case, all the `vtkm::cont::Algorithm` functions now
support automatically transferring objects that support the `ExecObject`
worklet convention. If any argument to any of the `vtkm::cont::Algorithm`
functions inherits from `vtkm::cont::ExecutionObjectBase`, then the
`PrepareForExecution` method is called with the device the algorithm is
running on, which allows these device-specific objects to be used without
the hassle of creating a `TryExecute`.
1. Have a per-thread pinned array for cuda errors
2. Check for errors before scheduling new tasks and at explicit sync points
3. Remove explicit synchronizations from most places

This commit adds several geometric constructs to vtk-m
in the `vtkm/Geometry.h` header. They may be used from
both the execution and control environments.
We also add methods to perform projection and Gram-Schmidt
orthonormalization to `vtkm/VectorAnalysis.h`.
See `docs/changelog/geometry.md` included in this commit
for more information.

Previously, the initilaizer_list of Vec had to be the exact
same number of values as the size of the Vec. Now, we also
accept a single value that is duplicated for all values in
the Vec. That allows you to more easily construct lists
of lists with repeated values.
Calling std::swap isn't legal from CUDA code, but the new vtkm::Swap
method is safe. It currently does a naive swap when compiling CUDA
code, and falls back to an ADL swap

Add constructors to the `vtkm::Vec` classes that accept
`std::initializer_list`. The main advantage of this addition is that it
makes it much easier to initialize `Vec`s of arbitrary length.

This commit adds a worklet and a filter to compute
signed integral measures of cells.
It also begins the practic of adding a markdown
changelog entry in `doc/changelog`. See the
changelog entry for details.
Reformat to look correct in 100 column display.
Update the copyright.
Remove and update some outdated specifications.
Remove description of formatting guidelines. There are done
automatically now.
Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and
EXEC_CONT.) Remove the inline from these macros so that they can be
applied to everything, including implementations in a library.
Because inline is not declared in these modifies, you have to add the
keyword to functions and methods where the implementation is not inlined
in the class.
