Jiri, I am glad that you liked the explodebreds site.  I looked at your definition and have to confess to both admiration and terror at the number and arrangement of wires you show.  I decided not to try to unpack this but to start from…

I wanted to add the School of Architecture at University of Virginia (explodebreps.wordpress.com)where I teach and also Univ. of Texas at Austin, Harvard, California College of the Arts.  While I know with certainty these schools, I have…

Giulio, Thank you so much for posting this marvelous component.  We have been struggling with shortest path definitions for the last six months and have yet to succeed.  Already I have been able to plot out pedestrian paths and paths of…

Hi, on the assumption that you are referring to the definition that I posted let me try to clarify. First, this was done on 7.055 and I am not aware that this has yet been superseded. The spiral component is the empty parameter component that will…

Well that was not so good on my first attempt to post a definition so I will try again

in the interests of conserving components, here is a slightly less complicated approach.

shortest paths through a point grid

Hello,I have been trying to develop a definition that would find the shortest path through a disrupted point grid.The purpose is to trace various urban flows (people, surface water, etc.).  This would seem to be the perfect project for Galapagos but so far the solution has remained out of reach. The attached file shows a point grid that has been randomly culled as a test case.  As a first step, I used the proximity component to determine the possible paths, setting this to only show orthogonal…See More

Damien, Thanks for taking the time to explain the mapping issues of the Delaunay component. I could see that this was the nature of your juggling, but at the time had not been able to fully process your specific actions. This is now clear and allows…

Let me explain what got "juggled" then. The key to all of this is properly organizing the path structure so that things match up in the way they need to, and this all centers around the resulting path structure of the Delaunay…

Alpha, I too am a fan of keeping componentry to a minimum. Thanks for adding this to the discussion. The replies from you and Damien plus some work I had been doing to get rid of redundant connections and invalid lines has turned the Delaunay module…

Robin Dripps replied to Robin Dripps's discussion 'The inner workings of Delaunay Triangulation'
Damien, Thanks so much. I now see from the Wikipedia site that the Delaunay is more complicated than I had realized but with this understanding it also becomes more powerful. Your def does clear up matters and in itself is quite neat although the…

Hi Robin, I realize Demien's Def is more clear in logic ,but we can remove some components to do the same thing.see below:

As far as how the Delaunay triangulation is calculated, I'd take a look on wikipedia as its got a pretty decent explanation... http://en.wikipedia.org/wiki/Delaunay_triangulation In regards to the output, you have all of the lines which make…
