Re: [boost] [Boost.Geometry] Extend spatial predicates to 1D segments?

Hi Lukas, Lukas Barth wrote:

I needed to query the 1D segments in the rtree for overlaps and got a nasty looking "not implemented" error when trying to compile. <snip> template struct disjoint : detail::disjoint::disjoint_segment {};

And, more importantly, I did not find a similar piece of code with a "1" as third template parameter. Thus, I assume that the 'disjoint' predicate is just not implemented for one-dimensional segments.

Yes, that's the correct place.

I added that predicate for my project, and now I'm wondering whether a full set of spatial predicates would be desirable for one-dimensional segments.

In other words: If I came up with a patch adding those predicates, would it be considered?

Every contribution would be appreciated. :) If you needed help: https://github.com/boostorg/geometry/wiki/Contribution-Tutorial With that said, note that in 1D a Segment would be the same as a Box. So you could store 1D Boxes instead and everything should work fine. AFAIR all predicates are implemented for ND cartesian Boxes. Regards, Adam
