Class SFCGAL::algorithm::BoundaryVisitor

MultiPolygon, PolyhedralSurface, TriangulatedSurface (same graph algorithm, edges without parallel or opposite)

MultiSolid : faced elimination

GeometryCollection : complex for heterogeneous collection (not supported in GEOS)

Member SFCGAL::algorithm::BoundaryVisitor::getBoundaryFromPolygons (const graph::GeometryGraph &g)

merge resulting edges

Member SFCGAL::algorithm::convexHull3D (const Geometry &g)

improve to handle collinear points and coplanar points

Member SFCGAL::algorithm::distance3D (const Geometry &gA, const Geometry &gB)

complete with solid Compute distance between two 3D Geometries

Precondition: gA is a valid geometry; gB is a valid geometry

Member SFCGAL::algorithm::distanceLineStringPolygon3D (const LineString &gA, const Polygon &gB)

same method than distancePointPolygon3D (unify if triangulate is available)

Member SFCGAL::algorithm::extrude (const Geometry &g, const Kernel::Vector_3 &v)

Improve extrude for 3D surfaces - Extrude only faces whose scalar_product(v,normal) > 0 and use Polyhedron union to get output geometries with a clean topology.

Member SFCGAL::algorithm::minkowskiSum (const Geometry &gA, const Polygon &gB, NoValidityCheck)

missing cases (union)

Precondition: gA and gB are valid geometries

Warning: @ No actual validity check is done.

Member SFCGAL::algorithm::straightSkeleton (const Geometry &geom, bool autoOrientation=true, bool innerOnly=false, bool outputDistanceInM=false, const double &toleranceAbs=EPSILON) -> std::unique_ptr< MultiLineString >

add supports for TriangulatedSurface and PolyhedralSurface

Parameters

geom	input geometry
autoOrientation	check and fix polygon orientation
innerOnly	Skip non-inner edges if requested
outputDistanceInM	whether to output the distance to border as M
toleranceAbs	Distance tolerance between returned points. A line must have a maximum distance of toleranceAbs.

Precondition: geom is a valid geometry

Exceptions

NotImplementedException If geom is a Polygon with point touching rings.

Class SFCGAL::graph::GeometryGraphBuilderT< Graph >

wrap vertex_descriptor, std::vector< edge_descriptor >, etc. in SharedPoint, SharedLineString, SharedPolygon, etc. and add utility method on the Graph?
