These mappers can be used to render cell sets as glyphs. The following
glyph types are available for scalar fields:
- Cube
- Sphere
- Axes
- Quads
For vector fields:
- Arrows
2fd8a9b9a Remove deprecated use of old unscoped enums in rendering
e051565d9 Use scoped enums in rendering classes

The enumerations in `vtkm::cont::Field::Association` were renamed in the
previous commit. The old names still exist, but are deprecated. Change
the rest of the code to use the new names.
This fix lerps the scalar field values at points of ray intersection,
ensuring rendering of quads pick the correct lerped color instead of
using the same color for the entire quad.
GCC 11 is having trouble compiling brigand.hpp at all, even before we
instantiate any templates. Since we no longer need it, let's get rid of
it. It was always placed in an internal namespace.
`RectilinearLocator::LocateCell` and `UniformLocator::LocateCell` assume
that the point in inside the bounds of the cell set, but may return a
cell location that does not exist, i.e., cell location that is outside
of the bounds of the cell set due to errors from floating point
operations.
This fix, given the assumption above, bounds the calculated cell
location to within the cellset by capping the indices to within the
limits.
The `DynamicCellSet` (and the related `DynamicCellSetBase`) are
deprecated and replaced with `UnknownCellSet` (and `UncertainCellSet`).
Thus, `UnknownCellSet` has some methods inherited from `DynamicCellSet`
but replaced with other functionality. These methods are now marked as
deprecated and their use is removed.
The `DynamicCellSet` class is now marked as deprecated (as is the header
that contains it), and all non-deprecated code is moved to its
`UnknownCellSet` replacement.
Also added a deprecation warning for the VariantArrayHandle.h header
file and deleted a couple inappropriate uses of it.
`UnknownCellSet` is an updated replacement for `DynamicCellSet`. The
next step in the replacement is to change `DataSet` to use the new
class.
Also replaced `DynamicCellSet` with `UnknownCellSet` in a few
places where `DynamicCellSet.h` was not directly included (and
therefore now no longer included at all). This change would have
to be made at some point anyway.
We have been doing a better job at hiding device code (and moving code
into libraries). Smoke out source that no longer needs to be compiled by
device compilers.
The `test_equal_images` function has been expanded to supply the
generated image in a `Canvas` or a `DataSet` in addition to a `View`.
Much of the templating code has been removed from `test_equal_images`
and most of the code has moved into the `vtkm_rendering_testing`
library.
The previous functions that enabled the render regression tests were
heavily templated, which required every test using rendering to
recompile the entire rendering system being used. Changed the interface
to not rely on templating so that the RenderTest method can be moved
into a library.
Also moved the options into a struct where they can be better managed.
The render testing functions tended to have lots of arguments that were
difficult to manage. Instead, created a single `struct` that holds all
the potential options. That way when someone specifies on option, it is
clear what option is being set.

By adding some XML tags to the test output, you can push the images used
and generated for tests to the dashboard where they will appear
alongside the test output.
Also made it more automatic to find alternate versions of test images.
Although it is generally wrong to try to call `ResetToBounds` with a
`Bounds` object that does not have a valid range, there are cases where
the range might not be valid. (For example, if `ResetToBounds` was
called in a routine that is rendering an empty scene, it would be best
not to crash.)
This commit makes `LineRenderer` and `TextRenderer` to batch line and
text rendering. Batching them has shown a significant speedup,
especially when usin CUDA.
If the camera is not a 3D camera, then it might be the case that the
calling code has not set the bounds in the Z direction. Allow this to
happen as long as you are not using a 3D camera.
The divide by zero happened when mapping a surface to a depth buffer.
Some rays terminated at the origin, which is a singularity in the
project matrix.
This might be indicative of a larger problem. Rays really shouldn't
terminate before the near plane.
There were apparently some fields copy/pasted from the 3D version were
not used in the 2D version (probably because they had no meaning). In
one case, one was erroneously normalized, and could cause a floating
point exception.
Deprecate `VirtualObjectHandle` and all other classes that are used to
implement objects with virtual methods in the execution environment.
Additionally, the code is updated so that if the
`VTKm_NO_DEPRECATED_VIRTUAL` flag is set none of the code is compiled at
all. This opens us up to opportunities that do not work with virtual
methods such as backends that do not support virtual methods and dynamic
libraries for CUDA.
Virtual methods were used in the `MeshConnectivity` classes for the
internal ray casting system. However, using virtual methods in the
execution environment is being deprecated.
This change replaces the virtual object with an object containing a
`Variant`. The `Variant` holds one of the supported mesh connectivities
and selects the correct one at runtime rather than jumping into a
virtual method.
