- this provides a better typesafe means of locating predefined cell
models than relying on strings. The lookup is now ptr() or ref()
directly. The lookup functions behave like on-demand singletons when
loading "etc/cellModels".
Functionality is now located entirely in cellModel but a forwarding
version of cellModeller is provided for API (but not ABI) compatibility
with older existing user code.
STYLE: use constexpr for cellMatcher constants
- with the xml append format it is possible to write raw binary
(instead of base64), but the writer becomes more complicated.
Either needs two passes to create, or need to allocate a block
of space for the header information (like VTK itself does) and
write later.
* internalWriter
* patchWriter
* surfaceMeshWriter
* lagrangianWriter
Also these special purpose ones:
* foamVtkWriteSurfFields
- this shifts responsibility away from caller to the individual writers
for knowing which file formats are supported and which file ending is
appropriate. When the writer receives the output format request,
it can elect to downgrade or otherwise adjust it to what it can
actually manage (eg, legacy vs xml vs xml-append).
But currently still just with legacy format backends.
- relocated to dedicated foamVtkOutput namespace. Make it easier to
obtain a formatter directly without a foamVtkOutput::outputOptions.
Make the logic clear within outputOptions (avoid previous, cryptic
bit masking). foamVtkOutput::legacy also becomes a namespace instead
of a class. Relocate commonly used things into src/fileFormats, leave
volField-related parts in src/conversion.
- provide headerType typedef in foamVtkFormatter, foamVtkOutput
- remove byteOrder and headerType constants from foamVtkFormatter
since the same strings can also be obtained from foamVtkPTraits
- additional convenience methods in foamVtkFormatter
Note: classes are prefixed with 'foamVtk' instead of 'vtk' to avoid potential
conflicts with VTK itself.
foamVtkCore
~~~~~~~~~~~
- General very low-level functionality.
foamVtkPTraits
~~~~~~~~~~~~~~
- Traits type of functionality for VTK
foamVtkOutputOptions
~~~~~~~~~~~~~~~~~~~~
- The various format output options as a class that can be passed to
formatters etc.
foamVtkCells
~~~~~~~~~~~~
- Intended for unifying vtkTopo and PV-Reader code in the future.
- Handles polyhedron decompose internally etc
foamVtkOutput, foamVtkFormatter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Output helpers.
- Selector for individual formatters.
Currently write all scalar data a 'float' (not 'double'). Can
revisit this in the future.
