Hi Peter,
I'm trying to figure out how to make work something similar to what you suggested, but I'm quite lost..
Of course the issues that I'm facing could be more because of my lack of knowledge about VOP's, so may I ask you any example of what you mentioned? Any links or papers?
Thank you for any help
Hey,
Use a pointcloud to get the closest point (if you do not know how to use pointclouds, then do a search here or on odforce for pointclouds - and you can put my username: pclaes in there as well as I've shared some examples on pointclouds in the past), add that to an attribute called “closest_point”.
In regards to the python, it will be a python sop that reads that closest point attribute and creates a new polygon between the current point and the closest point. There is a cookbook example that can show you how to generate some of that geometry.

I have done this in the past and made interesting spiderweb like shapes. The tricky bit is not so much straight wires, but curved wires. What starts out in a spiderweb as a straight wire can become a curved wire after it is pulled in different directions due to the tension in the web. Each segment is still straight though.
The cool bit is when you then use that “triangulate 3d” tool in a loop. As a little extra you can resample the newly generated polygons, potentially apply some noise and retriangulate using a shorter lookup distance. You then start to get a fractal nature into your patterns which is what makes it look cool.
