feat: Implement is_valid algorithm for polyhedral surfaces

6

This PR introduces support for the `is_valid` algorithm for polyhedral surface geometries. A polyhedral_surface is a 3D composite geometry formed by a collection of polygonal faces that meet at shared...

1

My `tc::geo::polygon` type is actually a **multi-polygon**, using a polygon type that is based on **int**, oriented **counter-clockwise** and **open** (not closed). I am using **boost 1.87.0**. Please consider the...

investigate remaining failurues in buffer_linestring_geo unit test

1

Tests are failing due to an error in buffer_linestring_geo unit tests. After bisecting the first commit that breaks that test is https://github.com/boostorg/geometry/commit/805ff654e869030c4ba70f37fad6c3825f59c077 Interestingly, the cmake tests are passing since that...

See #1404 It should specifically hunt for and test, in `include/boost/geometry/algorithms/detail/buffer/turn_in_piece_visitor.hpp` ``` if (piece.type == geometry::strategy::buffer::buffered_empty_side) { return false; ``` and what would go wrong there in some cases
