Adding lines connecting nearby points in a particle system creates an interesting effect, but it does get a little messy. I thought it would be interesting if the lines only connected the nearest particles to each, which would vary from point to point, and if the lines didn’t overlap or intersect. The result would be a nice mesh with varied density. Of course after putting the script together I turned it into a drawing machine. I’ll post more on exactly how this script works sometime soon.
In this Drawing Machine a series of particles spawned when the mouse is pressed move through a morphing Perlin noise flow field. They also slightly repel each other. The netting algorithm is applied to the particles to create the dark lines and their colors slowly shift. Many different factors effect the size and transparency of the points and lines in order to keep everything moving smoothly. Lines fade out as they get longer and fade out with the points they join.
