curveboolean - union of curves in script

I need to union closed curves in a script. I have several 2d shapes that sometime intersect and when they do I need to create their outline/boundary.I found a solution/hack in Grasshopper, but I need this scripted. Any idea how to resolve it?Here is an example:starting shapes.This is what I need:…See More

"Hi David. Plural was not typo.. If you have a look at the working attached definition (original thread) you might see what I'm trying to do. The script works, just wondering if it is the right way to do it or if there is a less resource heavy…"

"So one closed curve is divided into several closed curves? If that plural was a typo, aren't you just looking to change the seam of a closed curve? -- David Rutten david@mcneel.com Poprad, Slovakia"

Split closed curve into closed curves

Hi. I am trying to divide a 2D shape (closed Curve) at a point on its outline (decided by the input side/param) with a result of new closed Curves. The split will take place within a grid, here represented by WorldXY (could be a user set Plane) As far as I understand, no Curve method could do this? My take was the following: - create a planar surface from the shape curve - find the point on the curve - decide on split direction- add a splitting curve in direction, with boundingbox max as…See More

"Hi David. Thanks a lot for the tip, I'll see if I can make that work. I'll post some details when I implement it. Otherwise I thought I would have to implement something like the C# AForge.NET Genetics library... "

"One way of doing it inside Galapagos is to use a Gene Pool object with more sliders than you need and then discard a variable amount of them using -for example- Split List. -- David Rutten david@mcneel.com Poprad, Slovakia"

Genetic algorithms with dynamic genome amout

Hi.I am trying to write a script which, depending on the circumstances, will have a different number of genomes. As Galapagos works with static connections to sliders, I can't get it to work using Galapagos.Therefore I am looking for a C# library which will let me implement this in my c# script. Any tips/success stories?Cheers,EirikSee More

"thanks a lot David. Worked like a charm. Interesting to know that you can use a point and vector addition as a point parameter. "

Curve from Point3d and Vector3d

Hi. At a point I need to add a Curve of a certain length along a direction.I've made the following code work, but I am not sure how elegant it is, especially the conversion from Line to LineCurve to Curve. I need a Curve, because I do a CurveCurve intersection check later and this function doesn't accept a Line as a parameter. And since there is no constructor for Curve, I did it like this... directionVector *= distance; // set Vector length Line ln = new Line(point, directionVector); Curve…See More
