It replaces enriched.distance with factor. Factor is based on integer calculations, calculated in cart_intersect, from the passed robust points, so always trustable. We had to do this because without certain tests failed because of FP problems with distance (calculated with FP). This commit also greatly simplifies relate_collinear, where most things and checks are replaced by simple unified calculations. This is also based on robust fractions (but could have been done earlier). Many (but not all) testcases commented in previous commit are now uncommented again, they now work thanks to the fractions. There are also testcases uncommented which now work correctly using clang/Linux This commit breaks compiling disjoint (because of rescale), and running buffer (also because of rescale), and some more (probably all because or rescaling), this has to be fixed soon after. --- .../overlay/enrich_intersection_points.hpp | 15 +- .../detail/overlay/get_turn_info.hpp | 71 +-- .../algorithms/detail/overlay/turn_info.hpp | 9 + .../algorithms/detail/zoom_to_robust.hpp | 16 +- include/boost/geometry/core/tag.hpp | 3 + .../geometry/policies/relate/direction.hpp | 81 +++- .../policies/relate/intersection_points.hpp | 196 ++++++-- .../boost/geometry/policies/relate/tupled.hpp | 57 +-- .../strategies/cartesian/cart_intersect.hpp | 439 +++++++++--------- .../strategies/intersection_result.hpp | 65 +++ test/algorithms/difference.cpp | 16 +- test/algorithms/intersection.cpp | 19 +- test/algorithms/overlay/traverse.cpp | 20 +- test/algorithms/test_difference.hpp | 26 +- test/algorithms/union.cpp | 22 +- test/multi/algorithms/multi_difference.cpp | 2 - test/multi/algorithms/multi_intersection.cpp | 5 +- test/multi/algorithms/multi_union.cpp | 4 +- .../segment_intersection_collinear.cpp | 246 +++++++++- 19 files changed, 868 insertions(+), 444 deletions(-) diff --git a/include/boost/geometry/algorithms/detail/overlay/enrich_intersection_points.hpp b/include/boost/geometry/algorithms/detail/overlay/enrich_intersection_points.hpp index 6cf7d920d..2481b325e 100644 --- a/include/boost/geometry/algorithms/detail/overlay/enrich_intersection_points.hpp +++ b/include/boost/geometry/algorithms/detail/overlay/enrich_intersection_points.hpp @@ -79,9 +79,9 @@ template bool Reverse1, bool Reverse2, typename Strategy > -struct sort_on_segment_and_distance +struct sort_on_segment_and_ratio { - inline sort_on_segment_and_distance(TurnPoints const& turn_points + inline sort_on_segment_and_ratio(TurnPoints const& turn_points , Geometry1 const& geometry1 , Geometry2 const& geometry2 , Strategy const& strategy @@ -157,9 +157,13 @@ public : if (sl == sr) { // Both left and right are located on the SAME segment. +#if defined(BOOST_GEOMETRY_RESCALE_TO_ROBUST) + if (left.subject.fraction == right.subject.fraction) +#else typedef typename geometry::coordinate_type::type coordinate_type;

Enable touches() for other pairs of Geometries. Implement ready-to-use in the implementations of relate() less comparators of operations. Change the less comparator for L/A. Fix: handling of the entry/interior for some turn with MultiID which comes before union for some other turn with different MultiID. Finish the support for boost::mpl::vector<> as a complex StaticMask. --- .../algorithms/detail/relate/linear_areal.hpp | 86 ++---- .../detail/relate/linear_linear.hpp | 18 +- .../algorithms/detail/relate/relate.hpp | 27 +- .../algorithms/detail/relate/result.hpp | 54 +++- .../algorithms/detail/relate/turns.hpp | 32 +- include/boost/geometry/algorithms/touches.hpp | 279 +++--------------- test/algorithms/relate.cpp | 16 + test/algorithms/touches.cpp | 15 +- 8 files changed, 204 insertions(+), 323 deletions(-) diff --git a/include/boost/geometry/algorithms/detail/relate/linear_areal.hpp b/include/boost/geometry/algorithms/detail/relate/linear_areal.hpp index 880f1e483..d1ec480f5 100644 --- a/include/boost/geometry/algorithms/detail/relate/linear_areal.hpp +++ b/include/boost/geometry/algorithms/detail/relate/linear_areal.hpp @@ -239,13 +239,7 @@ struct linear_areal { // for different multi or same ring id: x, u, i, c // for same multi and different ring id: c, i, u, x - typedef turns::less - < - 0, turns::less_greater_op_for_other_same_m_diff_r - < - turns::op_to_int<0,2,3,1,4,0> - > - > less; + typedef turns::less<0, turns::less_op_linear_areal> less; std::sort(turns.begin(), turns.end(), less()); turns_analyser analyser; @@ -342,13 +336,7 @@ struct linear_areal else { // u, c - typedef turns::less - < - 1, turns::less_greater_op_for_other_same_m_diff_r - < - turns::op_to_int<0,1,0,0,2,0> - > - > less; + typedef turns::less<1, turns::less_op_areal_linear> less; std::sort(it, next, less()); // analyse @@ -460,10 +448,11 @@ struct linear_areal public: turns_analyser() - : m_previous_turn_ptr(0) + : m_previous_turn_ptr(NULL) , m_previous_operation(overlay::operation_none) , m_boundary_counter(0) , m_interior_detected(false) + , m_first_interior_other_id_ptr(NULL) {} template operations[op_id].seg_id; - //segment_identifier const& other_id = it->operations[other_op_id].seg_id; + segment_identifier const& other_id = it->operations[other_op_id].seg_id; const bool first_in_range = m_seg_watcher.update(seg_id); @@ -548,33 +537,20 @@ struct linear_areal { m_interior_detected = false; } + else if ( op == overlay::operation_union ) + { +// TODO: this probably is not a good way of handling the interiors/enters +// the solution similar to exit_watcher would be more robust +// all enters should be kept and handled. +// maybe integrate it with the exit_watcher -> enter_exit_watcher + if ( m_first_interior_other_id_ptr + && m_first_interior_other_id_ptr->multi_index == other_id.multi_index ) + { + m_interior_detected = false; + } + } } - // if the new linestring started just now, - // but the previous one went out on the previous point, - // we must check if the boundary of the previous segment is outside - // NOTE: couldn't it be integrated with the handling of the union above?
