Hi @Will. Sounds like you are coming from a Windows environment and looking for the equivalent of "the cube". That doesn't exist on MacOS, so like the other Unix-based systems on which IRIS is available you take a command line approach to connect to remote servers by connecting to a remote instance. Also, Studio is Windows-only, so with Mac development it's a great opportunity to migrate to VS Code with ObjectScript extensions.

Using the the handy utility from @Alex Woodhead I was able to get something working. As of now you can get the Point, Line and Polygon code from https://github.com/isc-rsingh/spatialiris but I can't guarantee those classes won't change in the future. I include demo code here to show:

  1. $LIST can be converted to a Python list using Py.Helper
  2. 2-dimensional $LISTs (a $LIST of $LISTs) didn't work without running them through the invoke ClassMethod you see below. 
  3. you can integrate with matplotlib to take advantage of the broad and deep range of functionality offered by probably the most popular graphics library around
Class geo.ToolsExample Extends %RegisteredObject
{

ClassMethod createPolygon() As geo.model.Polygon
{
    set l = ##class(geo.model.Line).%New()
    do l.addPoint(##class(geo.model.Point).%New(0.01,0.01))
    do l.addPoint(##class(geo.model.Point).%New(2.01,0.01))
    do l.addPoint(##class(geo.model.Point).%New(2.01,2.01))
    do l.addPoint(##class(geo.model.Point).%New(0.01,2.01))
    do l.addPoint(##class(geo.model.Point).%New(0.01,0.01))
    set polygon = ##class(geo.model.Polygon).%New()
    set polygon.line = l
    Return polygon
}

ClassMethod test()
{
    set polygon = ..createPolygon()
    set isin = ..PointInPolygon(polygon, ##class(geo.model.Point).%New(1.01,1.01))
    w isin,!
    set isout = ..PointInPolygon(polygon, ##class(geo.model.Point).%New(3.01,3.01))
    w isout,!
}

ClassMethod PointInPolygon(poly As geo.model.Polygon, pt As geo.model.Point) As %Boolean
{
    set mp = ##class(%SYS.Python).Import("matplotlib")
    set mpltPath = mp.path
    set polylist = poly.getAsList()
    set nothing = ##class(Py.Helper).toPyListOrString(polylist,.poly2)
    set point = ##class(Py.Helper).toPyListOrString(pt.getAsList())
    set path = ..invoke(mpltPath,poly2)
    Return path."contains_point"(point)
}

ClassMethod invoke(ByRef mpltPath As %SYS.Python, ByRef poly2) As %SYS.Python [ Language = python ]
{
    return mpltPath.Path(poly2)
}

}

Hello @Werner Noske. Now that VS Code has replaced Atelier as our cross-platform IDE (Studio is still supported), we have removed the plugin from the Eclipse Marketplace. The page you reference will soon make this clear as well. As @Dmitry Maslennikov says, we encourage developers to follow the guidance in this announcement and move to the VS Code platform if at all possible. Thanks!

Many code snippets exist for ObjectScript already. You can learn how they work in the VS Code docs here.  And if you're comfortable reading JSON, you can then go and see what's already implemented in the ObjectScript extension in this JSON file. If you don't find what you're looking for, I hope you'll consider building some of your favorites and submitting a pull request!
