- removed the previously added fileName type(), isDir(), isFile() methods.
- added optional bool parameter to isFile() function to explicitly
enable/disable the check for gzip files.
- fixed minor bugginess where the default usage of isFile() would result in
false positive matches.
- be slightly more stringent and use isDir() and isFile() instead of
exists() function when we actually know the expected type.
- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
'XX.size() <= 0' or for simpler coding.
It also has the same number of characters as '!XX.size()' and /might/ be
more readable
- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
when a simple 'XX.size()' suffices
- added boundBox(const tmp<pointField>&) constructor for use with
coordinate systems
- moved some methods from treeBoundBox to boundBox and use VectorSpace ops
//- Does the surface need an update?
virtual bool needsUpdate() const = 0;
//- Mark the surface as needing an update.
// May also free up unneeded data.
// Return false if surface was already marked as expired.
virtual bool expire() = 0;
//- Update the surface as required.
// Do nothing (and return false) if no update was required
virtual bool update() = 0;
The constructors for the derived classes should generally start in a
'expired' condition (ie, needsUpdate() == true) and rely on a subsequent
call to the update() method to complete the initialization. Delaying the
final construction as late as possible allows the construction of
surfaces that may depend on intermediate calculation results (eg,
iso-surfaces) and also avoids the unnecessary reconstruction of surfaces
between sampling intervals.
It is the responsibility of the caller to ensure that the surface
update() is called before the surface is used. The update() method
implementation should do nothing when the surface is already up-to-date.
- cuttingPlane and sampledPatch now use PrimitiveMeshedSurface for their
storage.
- cuttingPlane always triangulates since the cut faces tend to look quite
horrible anyhow.
- moved triangulation request out of sampledSurface to the inherited
classes. It might disappear anyhow.
