hi david i just posted a reply bu now i don't see it...(?) so i am really sorry if you get this twice... the graph is working really nicely, but it doesn't do exactly what i wanted to do. first, because i seem to be able to create only one area of density (instead of several) with the curves the graph provides. and secondly, i would like to be able to define these points of condensation in a more direct way, more connected to actual points in my rhino-geometry, as for example with different points that are referenced in gh, that locate the area of density.. (so where there is a point, the points on the curve get denser, and then gradually space out until the start getting denser towards the location of the next point). Also, the points should be arranged on the entire length of the curve (according to a certain preset number of points), and just change their spacing accordingly. (i tried to plug my distance measurer from point to curve into the eval, and it gave me a densely populated section of the curve, that moved its location on the curve with the movement of the point)
hope this wasn't too confusing! thank you so much, jessi On Mar 17, 9:28 am, David Rutten <[email protected]> wrote: > Hi Jessi, > > there are several approaches that might work for you.
