VTK-m has been updated to replace old per device worklet testing executables with a device
dependent shared library so that it's able to accept a device adapter
at runtime.
Meanwhile, it updates the testing infrastructure APIs. vtkm::cont::testing::Run
function would call ForceDevice when needed and if users need the device
adapter info at runtime, RunOnDevice function would pass the adapter into the functor.
Optional Parser is bumped from 1.3 to 1.7.
The field infrastructure has a "trait" that specifies the valid types
for the default active scalar field. Most filters have at most one input
field. The majority of the remaining filters use the same types for
inputs. There are some examples, however, where some auxiliary fields
use different types. This change adds a second template parameter to
FieldTraits to customize the valid types of the input scalar field to
different fields.
These changes are in anticipation of the removal of list specifier tags
on worklet ControlSignature arguments.
Previously, UnitTestProbe used a struct templated on the device adapter,
and that necessitated the use of the template keyword when using an
ambiguous type. These recent changes remove that template argument and
thus can cause a warning about using the template keyword in a non-
ambiguous type.
Now that the dispatcher does its own TryExecute, filters do not need to
do that. This change requires all worklets called by filters to be able
to execute without knowing the device a priori.
The CUDA compiler is giving us grief while compiling
UnitTestParticleAdvection.cxx even though the code is correct. Disable
it for now until we figure out what can be done with the compiler.
By making these helper classes ExecObject, they no longer need to have a
device to be constructed. This is important for future plans to make the
filters not determine a device adapter now that dispatchers no longer
require a device adapter.
This will make it easier to support integrators as an ExecObject.
One side effect is that the integrators and partical advection
are not templated by the type of the field.
Regardless of the type of the field, there is probably little reason to
compute particle advection with less than 64 bit floats to account for
accumulated errors. This will make it easier to use these classes.
It's a filter that Split sharp manifold edges where the feature angle
between the adjacent surfaces are larger than the threshold value.
When an edge is split, it would add a new point to the coordinates
and update the connectivity of an adjacent surface.
Ex. there are two adjacent triangles(0,1,2) and (2,1,3). Edge (1,2) needs
to be split. Two new points 4(duplication of point 1) an 5(duplication of point 2)
would be added and the later triangle's connectivity would be changed
to (5,4,3).
By default, all old point's fields would be copied to the new point.
Use with caution.
Rather than force all dispatchers to be templated on a device adapter,
instead use a TryExecute internally within the invoke to select a device
adapter.
Because this removes the need to declare a device when invoking a
worklet, this commit also removes the need to declare a device in
several other areas of the code.

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.

It takes CellSetStructured<2> and DynamicArrayHandle and uses CastAndCall
to resolve data type for pixels. Moved implementation to the RunImpl
function object.
ImageConnectivity worklet implements a parallel connected component
labeling algorithm for 2D structured grids/images. For each pixel,
it search for the pixel's 6 neighbors and classify them as the
same connected component if their corresponding "color" field have
the same value.
Previously, when a Worklet needed a scatter, the scatter object was
stored in the Worklet object. That was problematic because that means
the Scatter, which is a control object, was shoved into the execution
environment.
To prevent that, move the Scatter into the Dispatcher object. The
worklet still declares a ScatterType alias, but no longer has a
GetScatter method. Instead, the Dispatcher now takes a Scatter object in
its constructor. If using the default scatter (ScatterIdentity), the
default constructor is used. If using another type of Scatter that
requires data to set up its state, then the caller of the worklet needs
to provide that to the dispatcher. For convenience, worklets are
encouraged to have a MakeScatter method to help construct a proper
scatter object.
- PushOutOfDomain would loop over without exiting indefinately utilizing all max steps.
It's supposed to execute only once the particle goes out of spatio-temporal boundary.
- Removing the check for the steamlines polyline points to be same as the maxSteps from
the unit test, as if the particle has already taken some steps, then the polyline
points written out will always be lower than the total number of steps taken by the
current node.
- Adding code to support taking short steps (minimize boundary errors)
- Adding time of advection to the particle from the Integrator
- API changes for TakeStep
- TakeStep should only care about the maximum steps as it's a field on a Particle
- The check for out of temporal and spatial bounds has been moved to the Worklet
- Changing some of the internal APIs for supporting these new features/fixes
- Changing inheritance in the Integrators class to be more obvious than something convoluted
In some of the tests there was a field that was using a counting array.
This uses an integer as the value type and has a special implicit
storage type. Currently, this is likely to cause problems whenever it
runs into a cast and call of a dynamic array. For now, let's avoid
these.
In the near future we should have expanded virtual method capabilities
that will make it possible to support these atypical arrays.

Filters now support executing on a dataset to produce a result dataset
with automatic mapping of fields to the output dataset. Fields to map
can be selected using `vtkm::filter::FieldSelection` class, which provides
constructors to map all or no fields, along with a selection of fields.
This updates all tests to use the new filter API.

The ScalarsToColors is the first step in reproducing the color
capability that exists in VTK. The next step after this is to
provide a comparable lookup table.
1. Add option to copy user supplied array in make_ArrayHandle.
2. Replace Field constructors that take user supplied arrays with make_Field.
3. Replace CoordinateSystem constructors that take user supplied arrays with
make_CoordinateSystem.
Rob noticed a degridation in performance in some worklet tests when
ArrayCopy was added. I hypothesize that this slowdown is doing the array
copy with TBB instead of serial in the serial tests. (There have been
some checks in the existing code to suggest that some operations in TBB
can be slower than serial.) This change forces the array copy to be on
the device for which we are testing.
