Python 'Line-Line Intersection' Utility method

Hey Karembers,

I'm looking for the 'Line-Line Intersection' method, which should be in the Utilities namespace (I'm looking in the Karamba 1.1.0 Hacker's edition .chm) but can't manage to find the reference :/

Any clue ?

Cheers,

PS :I'll call it in Cython, hope that my free license takes that up

Hi Mac,

the 'LineLineIntersection'-componeet is one of those whose functionality has not yet been separated from the user-interface.

I will try to do that for Karamba 1.3.2.

Best,

Clemens

Hi Mac,

in Karamba 1.3.2 the intersection component makes use of the static method Karamba.Geometry.Line3Line3Intersection.solve(...) in order to do its job. It can be found in karambaCommon.dll.

This is the solve method of the component:

protected override void SolveInstance(IGH_DataAccess DA)
{
var ldist = INIReader.Instance().asDouble("limit_dist", default_limit_dist);
DA.GetData<double>(1, ref ldist);

var in_gh_lines = new List<GH_Line>();
if (!DA.GetDataList<GH_Line>(0, in_gh_lines)) return;
var lines = FromGH.Values(in_gh_lines);

var res = Line3Line3Intersection.solve(lines, ldist);

DA.SetDataTree(1, ToGH.Values(res.Item1, DA));
DA.SetDataList(0, ToGH.Values(res.Item2));
}

FromGH.Values and ToGH.Values are methods contained in Karamba.GHopper.Utilities which do the conversion from GH-types to Karamba-types and vice versa. They reside in karamba.gha.

Best,

Clemens
