Description
    Writes point data in glTF v2 format

    Two files are generated:
    - filename.bin  : a binary file containing all scene entities
    - filename.gltf : a JSON file that ties fields to the binary data

    The output can contain both geometry and fields, with additional support
    for colours using a user-supplied colour map, and animation of particle
    tracks.

    Controls are provided via the optional formatOptions dictionary.

    For non-particle track data:

    \verbatim
    formatOptions
    {
        // Apply colours flag (yes | no ) [optional]
        colours     yes;

        // List of options per field
        fieldInfo
        {
            p
            {
                // Colour map [optional]
                colourMap       <colourMap>;

                // Colour map minimum and maximum limits [optional]
                // Uses field min and max if not specified
                min             0;
                max             1;

                // Alpha channel [optional] (uniform | field)
                alpha           uniform;
                alphaValue      0.5;

                //alpha           field;
                //alphaField      T;
                //normalise       yes;
            }
        }
    }
    \verbatim

    For particle tracks:

    \verbatim
    formatOptions
    {
        // Apply colours flag (yes | no) [optional]
        colours     yes;

        // Animate tracks (yes | no) [optional]
        animate     yes;

        // Animation properties [optional]
        animationInfo
        {
            // Colour map [optional]
            colourMap       <colourMap>;

            // Colour [optional] (uniform | field)
            colour          uniform;
            colourValue     (1 0 0); // RGB in range [0-1]

            //colour          field;
            //colourField     d;

            // Colour map minimum and maximum limits [optional]
            // Note: for colour = field option
            // Uses field min and max if not specified
            min             0;
            max             1;

            // Alpha channel [optional] (uniform | field)
            alpha           uniform;
            alphaValue      0.5;

            //alpha           field;
            //alphaField      T;
            //normalise       yes;
        }
    }
    \endverbatim

Note
    When writing particle animations, the particle field and colour properties
    correspond to initial particle state (first data point) and cannot be
    animated (limitation of the file format).

The utility will now add field data to all tracks (previous version only
created the geometry)

The new 'fields' entry can be used to output specific fields.

Example

    cloud           reactingCloud1;

    sampleFrequency 1;

    maxPositions    1000000;

    fields          (d U); // includes wildcard support

STYLE: minor typo fix

Andrew Heather authored 3 years ago and Mark OLESEN committed 3 years ago

Users can now include additional controls via a new formatOptions dictionary.

- update coded templates with qualified names

GIT: add in missing PatchFunction1 constant() method

- was missed in a previous commit

- specify any of these

    ./Allwmake -build-root=...
    wmake -build-root=...
    FOAM_BUILDROOT=... wmake

  these specify an alternative root where build artifacts are to land.
  Currently only used as an alternative for the 'build/' hierarchy
  since the 'platforms/' target normally includes inputs as well.

  Possible use:
  ```
  (
      export WM_MPLIB="%{foam_mplib}"
      export FOAM_MPI="%{foam_mpi}"
      export MPI_ARCH_PATH="%{mpi_prefix}"

      export FOAM_BUILDROOT=/tmp/mpibuild
      export FOAM_MPI_LIBBIN="$FOAM_BUILDROOT/platforms/$WM_OPTIONS/lib/$FOAM_MPI"

      src/Pstream/Allwmake-mpi
   )
   ```

- exposed by the new embedded function handling.

  Requires local copies of dictionary content instead
  (similar to coded BCs handling)

BUG: incorrect formatting for expression function output

ENH: simpler copyDict version taking wordList instead of wordRes

- corresponds to the most common use case at the moment

ENH: expression string writeEntry method

- write as verbatim for better readability

- extendes the prefix syntax to handle '!' values.

  For example,  "(?!).*processor.*" or "(?!i)inlet.*"

- this revises the changes made in 95cd8ee7 to replace the
  SFINAE-type of handling of string hashes with direct definitions.

  This places a bit more burden on the developer if creating hashable
  classes derived from std::string or variants of Foam::string, but
  improves reliability when linking.

STYLE: drop template key defaulting from HashSet

- this was never used and `HashSet<>` is much less transparent
  than writing `HashSet<word>` or `wordHashSet`

- Generic thermophysical properties class for a liquid in which the
  functions and coefficients for each property are run-time selected.

  Code adapted from openfoam.org

STYLE: hostName() is short name, don't need parameter

- had lookups into the merge-point map instead of
  determining/remapping the duplicate points directly.
  The result was a jumble of face/point addressing.

STYLE: additional debug/verbosity comment for mergePoints

CONFIG: cleanup additional build-related env variables

- Function1, sampledSets, expressions, runTime selection tables

- marks if the value is considered to be independent of 'x'.
  Propagate into PatchFunction1 instead ad hoc checks there.

- adjust method name in PatchFunction1 to 'whichDb()' to reflect
  final changes in Function1 method names.

ENH: add a Function1 'none' placeholder function

- This is principally useful for interfaces that expect a Function1
  but where it is not necessarily used by a particular submodel.

TUT: update Function1 creation to use objectRegistry

Note - this resolves the reported dimensions error, but it is not clear
if this code (has ever?) run or if this change is appropriate...

ENH: coupling BC: allow Function1. Fixes #2277.

See merge request !507

Problem was extending the storage, copying the
original contents.

Updates for expressions to improve robustness and support functions, external context etc.

See merge request !501

- allows an additional HashTable of pointers to reference external
  content which not otherwise directly available via an
  objectRegistry.

  This could typically be used to provide a function-local "rho"
  to the expression evaluation.

- for cell quantities, these evaluate on the faceCells associated with
  that patch to produce a field of true/false values

- for face quantities, these simply correspond to the mesh faces
  associated with that patch to produce a field of true/false values

- similar idea to swak timelines/lookuptables but combined together
  and based on Function1 for more flexibility.

  Specified as 'functions<scalar>' or 'functions<vector>'.
  For example,

  functions<scalar>
  {
      intakeType table ((0 0) (10 1.2));

      p_inlet
      {
          type        sine;
          frequency   3000;
          scale       50;
          level       101325;
      }
  }

  These can be referenced in the expressions as a nullary function or a
  unary function.

  Within the parser, the names are prefixed with "fn:" (function).
  It is thus possible to define "fn:sin()" that is different than
  the builtin "sin()" function.

     * A nullary call uses time value
       - Eg, fn:p_inlet()

     * A unary call acts as a remapper function.
       - Eg, fn:intakeType(6.25)

- previously simply reused the scan token, which works fine for
  non-nested tokenizations but becomes too fragile with nesting.

  Now changed to use tagged unions that can be copied about
  and still retain some rudimentary knowledge of their types,
  which can be manually triggered with a destroy() call.

- provide an 'identifier' non-terminal as an additional catch
  to avoid potential leakage on parsing failure.

- adjust lemon rules and infrastructure:

  - use %token to predefine standard tokens.
    Will reduce some noise on the generated headers by retaining the
    order on the initial token names.

  - Define BIT_NOT, internal token rename NOT -> LNOT

- handle non-terminal vector values.
  Support vector::x, vector::y and vector::z constants

- permit fieldExpr access to time().
  Probably not usable or useful for an '#eval' expression,
  but useful for a Function1.

- provisioning for hooks into function calls. Establishes token
  names for next commit(s).

Function1 objectRegistry access

See merge request !499

Mark OLESEN authored 3 years ago and Mark OLESEN committed 3 years ago

    Returns a 0/1 value corresponding to function object trigger levels.

    Usage:
    \verbatim
        <entryName> functionObjectTrigger;
        <entryName>Coeffs
        {
            triggers        (1 3 5);
            defaultValue    false;  // Default when no triggers activated
        }
    \endverbatim

ENH: add reset() method for Constant Function1

ENH: allow forced change of trigger index

- the triggers are normally increase only,
  but can now override this optionally
