I have found the following “IntersectCurve” script and have a question regarding …(the whole script)
partial class Examples { public static Rhino.Commands.Result IntersectCurves(Rhino.RhinoDoc doc) { // Select two curves to intersect var go = new Rhino.Input.Custom.GetObject(); go.SetCommandPrompt("Select two curves"); go.GeometryFilter = Rhino.DocObjects.ObjectType.Curve; go.GetMultiple(2, 2); if (go.CommandResult() != Rhino.Commands.Result.Success) return go.CommandResult(); // Validate input var curveA = go.Object(0).Curve(); var curveB = go.Object(1).Curve(); if (curveA == null || curveB == null) return Rhino.Commands.Result.Failure; // Calculate the intersection const double intersection_tolerance = 0.001; const double overlap_tolerance = 0.0; var events = Rhino.Geometry.Intersect.Intersection.CurveCurve(curveA, curveB, intersection_tolerance, overlap_tolerance); // Process the results if (events != null) { for (int i = 0; i < events.Count; i++) { var ccx_event = events[i]; doc.Objects.AddPoint(ccx_event.PointA); if (ccx_event.PointA.DistanceTo(ccx_event.PointB) > double.Epsilon) { doc.Objects.AddPoint(ccx_event.PointB); doc.Objects.AddLine(ccx_event.PointA, ccx_event.PointB); } } doc.Views.Redraw(); } return Rhino.Commands.Result.Success; } }
When I put it into Visual Studio and started checking the data types I found some unusual things (from a beginner point of view) in the 14th row. var curveA = go.Object(0).Curve();
