proximity network

the idea is to generate a network out of proximities between a set of points. we loop through a random point cloud and search for the two closest points to the current point. they are connected by a line and we draw circles to the points with the radius of half of the distance to the currents` closest point.
the next step is to go into 3d. therefor we take the current and its closest two points and connect them by a polyline. further we adjust the poline`s brightness to its area. you get a 3d network of polylines which allowes one to think about creating spaces by only adjusting points` proximities. well, just a thought...
