)
Details
-
Base class:
RefinementTarget

Parameters:
threshold
- Refine segments whose homogeneity is less than this. Type: A real number in the range [0, 1].
choose_from
- Segments to consider. Type: An object of the
SegmentChooser
class.
Description
The Skeleton
refinement process is
ultimately driven by Segments
-- the refinement rule for each element is determined
solely by number and configuration of marked Segments
in the
element. CheckHeterogeneousEdges
directly
marks heterogeneous Segments
for refinement.
All Segments
whose homogeneity
is less than the given threshold
will be
refined, as long as they're in the set described by the
choose_from
parameter.
(choose_from
is a SegmentChooser object that can
restrict the scope of the refinement. Leave it set to FromAllSegments for unrestricted
operation.)
Figure 6.69 shows Segments
that have
been marked for refinement with threshold
=0.9
and choose_from
=FromAllSegments(). Figure 6.70 shows the result of
refining those segments (with the liberal Bisection rules).
