[*Bugfixes]
|
|
|
|
* bugfix: distance for multi-geometries ignored specified distance strategy. Fixed
|
|
* bugfix in difference for polygon/multi_polygon (reported 2011/10/24 on GGL-list)
|
|
* bugfix: raise exception for calculation of distances of multi-geometrie(s) where one of them is empty
|
|
* bugfix: multi DSV did not correctly use settings, fixed
|
|
* bugfix: self-intersections could sometimes be missed (introduced in 1.48), fixed
|
|
* bugfix: convex hull crashed on empty range (e.g. empty multi point), fixed
|
|
|
|
[*Solved tickets]
|
|
|
|
* [@https://svn.boost.org/trac/boost/ticket/6028 6028] Documentation: closure, fixed.
|
|
* [@https://svn.boost.org/trac/boost/ticket/6178 6178] Missing headerfile, fixed.
|
|
* [@https://svn.boost.org/trac/boost/ticket/6021 6021] convex hull of multipoint, fixed.
|
|
|
|
[*Additional functionality]
|
|
|
|
* support for line/polygon intersections and differences
|
|
* support for convert of segment/box of different point types
|
|
* support for append for multi point
|
|
* scalar functions (distance, area, length, perimeter) now throw an empty_input_exception on empty input
|
|
|
|
[*Documentation]
|
|
|
|
* updated support status
|
|
|
|
[*Internal changes]
|
|
|
|
* updates in specializations/not_implemented for distance/convert/assign/area
|
|
* move of wkt/dsv to io folder, making domains redundant
|
|
* strategy concepts assigned to zero to avoid clang warnings (patched by Vishnu)

[*Bugfixes]
|
|
|
|
* Robustness issue, in some circumstances the union failed to output. Fixed.
|
|
* Robustness issue, in some circumstances the calculated intersection point was outside the segment. Fixed.
|
|
* Concept issue, cartesian intersect didn't understand segments other than the provided one. Fixed.
|
|
* Sometimes self-intersections in linestrings were missed. Fixed.
|
|
* The fusion coordinate system was not registered correctly. Fixed.
|
|
|
|
[*Solved tickets]
|
|
|
|
* [@https://svn.boost.org/trac/boost/ticket/5726 5726] Segment intersection algorithm still assumes 'first', 'second' members
|
|
* [@https://svn.boost.org/trac/boost/ticket/5744 5744] Mistake in fusion adapt example
|
|
* [@https://svn.boost.org/trac/boost/ticket/5748 5748] Needed to include <boost/foreach.hpp>
|
|
* [@https://svn.boost.org/trac/boost/ticket/5954 5954] distance_pythagoras skips sqrt() step
|
|
|
|
[*Improvements on algorithms]
|
|
|
|
* Checking self-intersections is now not done automatically, this can blast performance.
|
|
* Besides that, checking self-intersections is made faster.
|
|
* Intersections now avoid outputting duplicate points. So they output the minimal set.
|
|
|
|
[*Additional algorithms]
|
|
|
|
* covered_by: within is defined as "within, not on boundary". covered_by is "within or on boundary"
|
|
|
|
[*Additional functionality]
|
|
|
|
* within: strategies can now be specified for within<point, box> and within<box, box>
|
|
* convert: a much broader range of conversions is supported
|
|
* assign: idem, (currently partly) synonym for convert (but reversed arguments)
|
|
|
|
[*Additional coordinate types]
|
|
|
|
* Basic (limited) support for Boost.Rational
