S2 Geometry Files

Interface Changes

• Remove glog and gflags dependencies. Now abseil-cpp is used.
• ABSL_LOG macros are used instead of S2_LOG
  • The indirection could be added back if requested
• ABSL_CHECK macros are used instead of S2_CHECK
• S2_DEFINE_ now forwards to ABSL_FLAG
• New files:
• s2chain_interpolation_query
• s2density_tree
• s2gmock_matchers
• s2fractal
• s2shapeutil_count_vertices
• s2shapeutil_edge_wrap
• New S2Shape functions:
• Incoming
• Outgoing
• IncidentOn
• Remove S2Shape::id()
• New predicates in s2predicates.h
• S2Region::GetCellUnionBound is now pure virtual
• Replace S2Testing::Random, which was based on random(3), with new s2random:: namespace, based on abseil-cpp's random library. This removes the use of global state.
• Use int64_t instead of int64, etc.
• constexpr fixes
• Remove some old SWIG workarounds.
• Now requires abseil-cpp LTS 20240116
• S2Shape derived classes: Add decoding interface with S2Error
• S2Error: Interface is now similar to absl::Status, just with a different error code type. In the future, this will probably be replaced by absl::Status.
• S2CellId: Made some functions constexpr
• s2edge_crossings: Fix CompareEdges for a case that never happens
• S2Polygon uses new S2LegacyValidQuery to validate geometry.
• S2ValidationQuery: New class
