This commit makes `LineRenderer` and `TextRenderer` to batch line and
text rendering. Batching them has shown a significant speedup,
especially when usin CUDA.
Previously, the check for visit points with cells for `CellSetExtrude`
only looked at the count of incident cells. This expands the check to
make sure that it actually returns the expected cells.
Scheduling topology map workets for `CellSetExtrude` always worked, but
the there were indexing problems when a `Scatter` or a `Mask` was used.
This has been corrected, and now `Scatter`s and `Mask`s are supported on
topology maps on `CellSetExtrude`.
The superclass method `CellSetExplicit::GetCellShape()` is marked
deprecated because it is a slow way to access the cell shape. However,
this deprecation is causing a warning with MSVC when implementing the
subclass `CellSetSingleType`'s override of that method (which is not
slow). Suppress this warning.
Because `CellSetExplicit` is a templated class, the implementation of
most of its features is part of the header files. One of the things that
was included was the code to build the reverse connectivity links. That
is, it figured out which cells were incident on each point using the
standard connections of which points comprise which cells.
Of course, building these links is non-trivial, and it used multiple
DPPs to engage the device. It meant that header had to include the
device adapter algorithms and therefore required a device compiler. We
want to minimize this where possible.
To get around this issue, a non-templated function was added to find the
reverse connections of a `CellSetExplicit`. It does this by passing in
`UnknownArrayHandle`s for the input arrays. (The output visit-points-
with-cells arrays are standard across all template instances.) The
implementation first iterates over all `CellSetExplicit` versions in
`VTKM_DEFAULT_CELL_SETS` and attempts to retrieve arrays of those types.
In the unlikely event that none of these arrays work, it copies the data
to `ArrayHandle<vtkm::Id>` and uses those.
Make it more clear that ScanExtended increases the array size by
1, what ranges the exclusive and inclusive scan cover, and the
features of the first and last entries.
There was a case where a VTK-m exception was caught and then used in a
logging message. That is fine, but if VTK-m logging is turned off, that
code is removed and the exception variable goes unused.
There was a time when it was common to have logging turned off in VTK-m,
but now it is almost always on. There is one old-style dashboard that
has logging turned off and is giving a warning about this variable not
being used. It went unnoticed because the dashboard was down at the
time. This should fix the issue.
`ConvertNumComponentsToOffsets` has been changed to provide a pre-
compiled version for common arrays. This helps with the dual goals of
compiling less device code and allowing data set builders to not have to
use the device compiler. For cases where you need to compile
`ConvertNumComponentsToOffsets` for a different kind of array, you can
use the internal `ConvertNumComponentsToOffsetsTemplate`.
For no particularly good reason, there were two functions that converted
and array of counts to an array of offsets: `ConvertNumComponentsToOffsets`
and `ConvertNumIndicesToOffsets`. These functions were identical, except
one was defined in `ArrayHandleGroupVecVariable.h` and the other was
defined in `CellSetExplicit.h`.
These two functions have been consolidated into one (which is now called
`ConvertNumComponentsToOffsets`). The consolidated function has also been
put in its own header file: `ConvertNumComponentsToOffsets.h`.
Normally, backward compatibility would be established using deprecated
features. However, one of the things being worked on is the removal of
device-specific code (e.g. `vtkm::cont::Algorithm`) from core classes like
`CellSetExplicit` so that less code needs to use the device compiler
(especially downstream code).
Part of this change removed unnecessary includes of `Algorithm.h` in
`ArrayHandleGroupVecVariable.h` and `CellSetExplicit.h`. This header had to
be added to some classes that were not including it themselves.

The triangulate and tetrahedra worklet implementations were for some
reason grabbing raw arrays out of `CellSetExplicit` and using those for
lookup tables. Rather than do that, simply use a
`WorkletVisitCellsWithPoints` automatically provide the values of these
cells. The advantage of this approach is that it simplifies the code and
also generalize it to cell sets that do not provide this explicit
representation. For example, the new implementation also works with
`CellSetExtrude`.
The code path for doing either tetrahedralization or triangulation on a
CellSetSingleType was not actually doing any work. Changed the worklet
implementation so that these work on CellSetExplicit with any template
parameters (which includes CellSetSingleType).
a2a8dcdfd Allow a `const ArrayHandle` to be reallocated

Previously, the `Allocate` method of `ArrayHandle` was _not_ declared as
`const`. Likewise, the methods that depended on `Allocate`, namely
`ReleaseResources` and `PrepareForOutput` were also not declared `const`.
The main consequence of this was that if an `ArrayHandle` were passed as a
constant reference argument to a method (e.g. `const ArrayHandle<T>& arg`),
then the array could not be reallocated.
This seems right at first blush. However, we have changed these methods to
be `const` so that you can in fact reallocate the `ArrayHandle`. This is
because the `ArrayHandle` is in principle a pointer to an array pointer.
Such a structure in C will allow you to change the pointer to the array,
and so in this context it makes sense for `ArrayHandle` to support that as
well.
Although this distinction will certainly be confusing to users, we think
this change is correct for a variety of reasons.
1. This change makes the behavior of `ArrayHandle` consistent with the
behavior of `UnknownArrayHandle`. The latter needed this behavior to
allow `ArrayHandle`s to be passed as output arguments to methods that
get automatically converted to `UnknownArrayHandle`.
2. Before this change, a `const ArrayHandle&` was still multible is many
way. In particular, it was possible to change the data in the array
even if the array could not be resized. You could still call things
like `WritePortal` and `PrepareForInOut`. The fact that you could
change it for some things and not others was confusing. The fact that
you could call `PrepareForInOut` but not `PrepareForOutput` was doubly
confusing.
3. Passing a value by constant reference should be the same, from the
calling code's perspective, as passing by value. Although the function
can change an argument passed by value, that change is not propogated
back to the calling code. However, in the case of `ArrayHandle`,
calling by value would allow the array to be reallocated from the
calling side whereas a constant reference would prevent that. This
change makes the two behaviors consistent.
4. The supposed assurance that the `ArrayHandle` would not be reallocated
was easy to break even accidentally. If the `ArrayHandle` was assigned
to another `ArrayHandle` (for example as a class' member or wrapped
inside of an `UnknownArrayHandle`), then the array was free to be
reallocated.
Added the following form of `ArrayCopy`:
```cpp
VTKM_CONT_EXPORT void ArrayCopy(
const vtkm::cont::UnknownArrayHandle& source,
const vtkm::cont::UnknownArrayHandle& destination);
```
Note that the destination array is a constant reference. This is
actually OK because you can change the contents of an
`UnknownArrayHandle` (as long as you don't change the array being
referenced). The main motivation for this change is to allow you to call
this form of `ArrayCopy` while passing in a `ArrayHandle` as the second
argument. C++ will automatically make the conversion, but the function
has to accept a const reference for it to be passed correctly.
Note that there is still a form of `ArrayCopy` that accepts a non-const
reference to the destination array. The two arrays behave the same
except for one difference. For the non-const version, if the
`UnknownArrayHandle` does not already point to an array (i.e. is not
valid), a new array will be created and placed in the destination
object. However, because this cannot be done for a const reference, an
exception is thrown instead.

By default, the `FilterDataSet` class will iterate over all fields and
use `CastAndCall` on each one to call the subclass' mapping function
with the appropriate array type.
This only works if the array is of a known type. If it is not
`CastAndCall` throws an exception. However, having the entire filter
exception out just because one field cannot be converted does not make
sense. Instead, catch the exception, log a warning, and drop the field.
The reason why we did not support shared libraries when CUDA compiles
were on is that virtual methods require a special linking step to pull
together all virtual methods that might be called. I other words, you
cannot call a virtual CUDA method defined inside a library. This
requirement goes away when virtuals are removed.
Also removed the necessity of using seprable compilation with cuda.
Again, this is only needed when a CUDA function is defined in one
translation unit and used in another. Now we can enforce that all
translation units define their own CUDA functions.
Also, suppress warnings in cuda/internal/ExecutionPolicy.h
This is where we call the thrust algorithms. There must be some loop
where it, on some code path, calls back a host function. This must be in
an execution path that never happens. The thrust version has its own
suppress, but that does not seem to actually suppress the warning (it
just means that the warning does not tell you where the actual call is).
Get around the problem by suppressing the warnings in VTK-m.
