- comprises a few different elements:
FilterField (currently packaged in PatchFunction1Types namespace)
~~~~~~~~~~~
The FilterField helper class provides a multi-sweep median filter
for a Field of data associated with a geometric point cloud.
The points can be freestanding or the faceCentres (or points)
of a meshedSurface, for example.
Using an initial specified search radius, the nearest point
neighbours are gathered and addressing/weights are built for them.
This currently uses an area-weighted, linear RBF interpolator
with provision for quadratic RBF interpolator etc.
After the weights and addressing are established,
the evaluate() method can be called to apply a median filter
to data fields, with a specified number of sweeps.
boundaryDataSurfaceReader
~~~~~~~~~~~~~~~~~~~~~~~~~
- a surfaceReader (similar to ensightSurfaceReader) when a general
point data reader is needed.
MappedFile
~~~~~~~~~~
- has been extended to support alternative surface reading formats.
This allows, for example, sampled ensight data to be reused for
mapping. Cavaet: multi-patch entries may still needs some work.
- additional multi-sweep median filtering of the input data.
This can be used to remove higher spatial frequencies when
sampling onto a coarse mesh.
smoothSurfaceData
~~~~~~~~~~~~~~~~~
- standalone application for testing of filter radii/sweeps
