make each node connect to the nearest grid intersection

Do you mean draw a line from each node to the nearest intersection? Or do you want to “snap” the points to the nearest grid intersection?

If you are trying to snap points to a regular grid, you can use snap-closest based on modulo (%) – see this example:

How to snap mouse to a shape/coordinate?

The simplest way to snap in 2D is %. Define your grid step, then subtract the modulo of that from your current location to snap, no modulo for free motion. int gstep = 10; void draw(){ background(128); if (keyPressed){ ellipse(mouseX, mouseY, 10, 10); } else { ellipse(mouseX - mouseX%gstep, mouseY - mouseY%gstep, 10, 10); // snap } lines(); } void lines(){ for(int x=0; x<=width; x+=gstep) line(x,0,x,width); for(int y=0; y<=height; y+=gstep) line(0,y,height,y); } This as…
