In order to compile the contour filter more efficiently, we split the contour filter into two separate translation units, corresponding to the new filters ContourFlyingEdges and ContourMarchingCells. The API for Contour filter is left totally unchanged, and tries to use flying edges if the dataset is structured and uniform.
All three contour filters inherit from the `AbstractContour` class, providing utility methods used in the implementations.
Originally, most of the sources used constructor parameters to set the
various options of the source. Although convenient, it was difficult to
keep track of what each parameter meant. To make the code more clear,
source parameters are now set with accessor functions (e.g.
`SetPointDimensions`). Although this makes code more verbose, it helps
prevent mistakes and makes the changes more resilient to future changes.
The previous version of BenchmarkInSitu added arguments to its argv list
by using `strdup`. However, this method will leak memory, which is not
great. Replace this with a safer mechanism that will properly delete
memory at the end of the program (and satisfy any memory analyzers).
This also fixes a warning from MS about `strdup` being deprecated.
Previous version had a hard-coded loop for updating the dataset. This change relenquishes control over to google benchmarks. Running it from the command-line will iterate each sub-benchmark a different number of iterations depending on how long each individual test takes. The number of iterations can be increased (but not controlled) by increasing the minimum time for each test. Alternatively, using the "repetitions" argument, you can control exactly how many times the benchamrks are run.
See the README for InSitu that throughly documents the arguments.
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.
