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.
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.
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.
Deprecated the `CellLocator` class and made all methods of the
other `CellLocator` classes non-virtual. General locators can
still use the `CellLocatorGeneral` class, but this class now
only works with a predefined set of locators. (The functionality
to provide a function to select a locator has been removed.)
There are several places in the ray casting library that require
operating on a field that we know is a scalar field. Previously, these
were all independently cast to an uncertain array of the limited types.
Rather than have independent calls everywere, make a consolidated
function that does the same operation for everyone.
This fixes an issue with using a deprecated version of a method. It also
makes it possible to quickly change types in the future.
Cell operations like interpolate and finding parametric coordinates can
fail under certain conditions. Typically these call RaiseError on the
worklet. But that can make a worklet unstable, so provide paths where no
error is raised.
The timer class now is asynchronous and device independent. it's using an
similiar API as vtkOpenGLRenderTimer with Start(), Stop(), Reset(), Ready(),
and GetElapsedTime() function. For convenience and backward compability, Each
Start() function call will call Reset() internally and each GetElapsedTime()
function call will call Stop() function if it hasn't been called yet for keeping
backward compatibility purpose.
Bascially it can be used in two modes:
* Create a Timer without any device info. vtkm::cont::Timer time;
* It would enable timers for all enabled devices on the machine. Users can get a
specific elapsed time by passing a device id into the GetElapsedtime function.
If no device is provided, it would pick the maximum of all timer results - the
logic behind this decision is that if cuda is disabled, openmp, serial and tbb
roughly give the same results; if cuda is enabled it's safe to return the
maximum elapsed time since users are more interested in the device execution
time rather than the kernal launch time. The Ready function can be handy here
to query the status of the timer.
* Create a Timer with a device id. vtkm::cont::Timer time((vtkm::cont::DeviceAdapterTagCuda()));
* It works as the old timer that times for a specific device id.
The script fixed up most of the issues. However, there were some
instances that the script was not able to pick up on. There were
also some instances that still needed a means to select types.
Visual Studio default toolset uses 32bit executables for compiling which
means that if it uses more than 4GB of memory per instance it crashes.
By moving the ConnectivityTracer into a separate compilation unit we
can help out the compiler.
This also improved compilation times and library size:
Old:
build time (j8): 48.62 real
lib size: 6.2MB
New:
build time (j8): 41.31 real
lib size: 5.0MB
