95454e4c8e [traverse] redo, isolated MUST be checked. Checking interior/exterior ring is 
then redundant again, besides that it does not work for differences.
This breaks case_134 but that must be fixed differently.

After this change, recursive_polygons test is flawless
w.r.t. intersections/unions (validity/with self turns not yet checked)

bd16305a72 [overlay] remove original behaviour to discard turns colocated with blocked turns, 
because this stops generating interior rings in certain configurations, and
it is, in the meantime, handled differently in cluster traversal.
Fixes cases like new case #case_recursive_boxes_51

0853342320 [traverse] fix #case_58_multi and #case_134_multi by verifying connected

ecae306146 [traverse] generalize pattern for colocated interior rings by making 
cases with multiple rings (#case_134_multi) possible. It also does
not check for isolated anymore but instead checks interior/exterior rings
and region_ids

b0cf8ffb59 [traverse] extend handling specific case of cc/ii with another variant,

463f778a36 [overlay] fix cases with two parallel interior rings, one touching 
the exterior ring, by adding a special case for this. This solves
nearly all robustness (recursive_polygon) now.

081860e8dd [sort_by_side] fix (rare) cases where two froms arrive at a turn, 
but only one leaves the next turn. This simplifies state to just a boolean.
This fixes cases like case_recursive_boxes_46 for union

ff77e78562 [test][setops] Add failing test cases. 2016-06-21 16:45:46 +02:00
Barend Gehrels
3d5906f1e8 [traversal] revised switch detector because could not get previous approach 
working for the last cases and for newly created connected interior rings. The new approach is much simpler and based
on regions (connected rings, connected via interiors) and works for almost
all cases including newly created connected interiors. Last cases still to
be checked though.

It does not traverse through turns, but instead navigates through rings

there but detect source-switching

85e0755ccd [traverse][fix] use two passes, in first pass avoid uu turns to get 
the interior rings right at starting points. Second pass use uu, but
only switch source if there are only uu turns found. This fixes most
of the simple cases (complex cases can still go wrong)

d256e57487 [overlay] now we can/need to remove functionality to discard turns 
colocated with uu and the same ring.
This breaks one case (# case_recursive_boxes_23) but repairs many (about 50%
of the wrong cases in robustness test)

5f028b0b04 [overlay] split polygon_count in left_count/right_count, this is necessary 
for some cases (ex. #case_recursive_boxes_29). Also, necessary, now that
startable is defined, don't discard colocated cc in clusters, they are
sometimes necessary.
