- when writing surface formats (eg, vtk, ensight etc) the sampled
surfaces merge the faces/points originating from different
processors into a single surface (ie, patch gatherAndMerge).
Previous versions of mergePoints simply merged all points possible,
which proves to be rather slow for larger meshes. This has now been
modified to only consider boundary points, which reduces the number
of points to consider. As part of this change, the reference point
is now always equivalent to the min of the bounding box, which
reduces the number of search loops. The merged points retain their
original order.
- inplaceMergePoints version to simplify use and improve code
robustness and efficiency.
ENH: make PrimitivePatch::boundaryPoints() less costly
- if edge addressing does not already exist, it will now simply walk
the local face edges directly to define the boundary points.
This avoids a rather large overhead of the full faceFaces,
edgeFaces, faceEdges addressing.
This operation is now more important since it is used in the revised
patch gatherAndMerge.
ENH: topological merge for mesh-based surfaces in surfaceFieldValue
- previously introduced `getOrDefault` as a dictionary _get_ method,
now complete the transition and use it everywhere instead of
`lookupOrDefault`. This avoids mixed usage of the two methods that
are identical in behaviour, makes for shorter names, and promotes
the distinction between "lookup" access (ie, return a token stream,
locate and return an entry) and "get" access (ie, the above with
conversion to concrete types such as scalar, label etc).
