577c3bcfe4 [traverse] use same method for finding index; this fixes 
the last uu case in union_multi (and is better anyways)

83320f528e [traverse] move loop to separate method to be shared later 2016-02-27 18:08:18 +01:00

0bd3944652 [traverse] don't travel again over visited arcs in clusters. This fixes 
(again, after breaking) all cases for difference/intersection and no new
errors for union/buffer

d0f584e6f3 [traverse] fix cases where there is a choice between two equally suited 
arcs from a cluster - if one is the starting point, take that one

05c789e77e [buffer][traverse] fix uu for buffer 2016-02-17 12:38:34 +01:00

e30fd1ca4c [traverse] fix case for buffer having only cc (in the whole cluster). 
For a cc operation, main_rank 0 is OK

c4c180bb7d [union] instead of checking uu, count open spaces to support also 
conbined touching turns without a uu

41518b6ac3 [traverse] use count_left/count_right to get first requested turn 
in clusters

1ea05c3539 [traverse] fix subject/origin, which did not work for buffer 
Now the previous point is taken (this might in theory be colocated!)

5a35924616 [traverse] use index instead of source_index to determine subject 
(in relation with previous commit: use indexes instead of iterators, part 2)

24908b7636 [traverse] go to index instead of iterator (part 1) 2016-02-03 12:10:54 +01:00

b55eec5b7e [buffer] fix new traverse approach for buffer, it should take the 
first segment if encountering an early finish

ed6db710ce [buffer] repair compiling: adapt buffer backtrack policy to recent change,

5df1a05e34 [formulas] Make the andoyer_inverse formula more robust. 2016-01-19 00:30:50 +01:00
Adam Wulkiewicz
eba433ee06 [formulas] Fix/improve andoyer_inverse formula for antipodal and nearly antipodal points. 
The results returned by this formula are now also consistent in a way that the closer points are to being antipodal the closer are the results to edge-case results.

a236ba3391 [overlay] add counts to enrichtment info, this avoids it to be redone, 
and use it in traverse omitting the operation condition
 2016-01-13 15:58:51 +01:00
Barend Gehrels
8364aed91b [intersection] fix cases where intersection has to travel through uu/ux 2016-01-13 12:49:47 +01:00
Barend Gehrels
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)
 2016-01-13 10:52:04 +01:00

c268bb2fd4 Minor change, check on cluster ids 2016-01-10 19:14:31 +01:00
Barend Gehrels
c74ff4c0df [overlay] remove functionality for colocated cc turns, recently added, 
but now redundant again.
(In hindsight I should have added the "startable" functionality first)
 2016-01-10 19:12:55 +01:00
Barend Gehrels
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.
 2016-01-10 19:06:34 +01:00
Barend Gehrels
01df9eacbb [overlay] fix implementation of startable flag, it should start if there 
are 1 (union) or 2 (intersection) polygons on right hand
 2016-01-10 13:32:08 +01:00
Barend Gehrels
e4624dad28 [union] remove discarded lonely uu turns from cluster 2016-01-09 20:09:35 +01:00
Barend Gehrels
7931e0445b [intersection] now discarded uu turns outside clusters, they block traversal 2016-01-09 19:31:19 +01:00
Barend Gehrels
3a9713b267 [sort by side] fix index 2016-01-09 19:15:44 +01:00
Barend Gehrels
b7a16976c9 [overlay] handle startable functionality for traverse w.r.t. clusters 
This has a small regression on 5 cases in multi_difference, to be inspected,
and can change the number of holes due to commenting handle_touch
 2016-01-09 13:39:28 +01:00
Barend Gehrels
df2c1f35bc [sort by side] remove rank, not used anymore 2016-01-09 10:16:48 +01:00
Barend Gehrels
f377eebf8c [traverse] instead of combination uu/ux for specific behaviour, 
now check on uu/* (any turn in combination with uu) for unionts
 2016-01-08 18:28:38 +01:00
Barend Gehrels
0d3ef5e3e9 [intersection] discard turns colocated with uu too (these turns are based on 
invalid input)
 2016-01-07 19:34:08 +01:00
Barend Gehrels
59125adb8d [intersection] don't exclude ux for intersection because it is necessary 
to block certain paths
 2016-01-07 18:59:05 +01:00
Barend Gehrels
98f26765e7 [union] change solution for reversed clusters (uu/ux only), 
this fixes the new case #case_recursive_boxes21

This fixes again all current multi union/intersection/difference and all union
 2016-01-06 22:29:52 +01:00
Barend Gehrels
71fbcd8aaf [traverse] remove now redundant condition, clusters never have discarded turns 2016-01-06 18:19:40 +01:00
Barend Gehrels
32ddae6c0d [union] handle clusters with uu-only and halfway incoming arcs 2016-01-06 18:18:18 +01:00
Barend Gehrels
c9836ca17f [union] handle clusters with uu/ux combined 2016-01-06 17:18:05 +01:00
Barend Gehrels
2c1a7b7f40 [union] fix simple cases having two colocated uu turns 
(appearing now that uu turns are included)
 2016-01-06 16:52:19 +01:00
Barend Gehrels
b272e9f615 [intersection] also for intersection, uu turns have to be included to 
make proper decisions on clusters.
This also removes switch_source initialization (which is false anyway)

This fixes all known cases for multi union/intersection again,
except for the number of clips. Difference still has one area error
