Line-line interactions in Kangaroo

Hi Peyman,

I do not have Kangaroo installed, and your screenshot is not of high resolution, but judging by it, the issue is not with "Remove curve duplicates" component. I assume that the issue is that you are trying to convert the unique polylines you get from "UC" output to lines.
Grasshopper's "Line" parameter can not automatically do that. You have to shatter the polylines to its segments:

Hi Djrodje,

Thank you for your comment, i downloaded the component, it is very cool but i still have the same problem. what do you think?

Hi Peyman.
For curve geometries more complex than straight lines, you can use the Remove curve duplicates component.

Hi Daniel,

I looked at the example, i am wondering if we make the input line a bit more complicated, like using a kind of multi segmented line, then it doesn't work and only works with one segment lines. what can be the solution for simulation of collision between more complicated geometries? is it possible or not?

Many thanks

Hi Peyman - I just added an example of this in Kangaroo2 here:

Hi Daniel,

Is there any definition or tutorial to learn how line line interaction component works?
I surfed a lot on the net but couldn't find something. I just something to see how it works to make a collision between series of lines.

Daniel - I was asked to do a particle packing simulation for a scientist once.  He asked "Can you do M&M (as in the candy) packing in a predefined container?"

I totally agree with Jacek Jaskólski!

hey daniel,

awesome work as always .. just an idea, since intuitive design tools in the best case are superfast (at least for me) : what about a naive parallelization using the .NET framework 4 parallel libraries? very easy to use, also robust.. dont require a too deepening knowledge (as you speak of finding smart ways to check for collisions, e.g. this loop maybe could just be parallelized with a Parallel.For<>() or something similar, and could speed up things with kangaroo 2-8 times ..!

of course, CUDA would be another dimension to parallelize on the graphics cards shaders, but more cumbersome and limited to certain nvidia users..

btw. how's work with the LEAP? i also applied & ordered ..! 

best

Robert
