The effect is kind of hard to distinguish. But what I see is this:

1. A horizontal and vertical grid.
2. The vertical lines fade between visible to barely visible (like a 'black bar moving over the planet') based on y-location.
3. The whole thing is kind of glowy.

The first can be done with lines.
The second can be done with the stroke() color / transparency.
The third can be done in different ways, but for example by blurring an offscreen buffer with the same image.

As your attempt, below is a quick 2D sketch that shows in a nutshell these three effects. Press SPACE to toggle the glow.

Code Example

1. int dim = 10;
2. int rowSize, columnSize;
3. PImage glow;
4. boolean glowOn;
5.  
6. void setup() {
7.   size(800, 600);
8.   rowSize = height/dim;
9.   columnSize = width/dim;
10. }
11.  
12. void draw() {
13.   background(0);
14.   if (glow != null && glowOn) {
15.     image(glow, 0, 0);
16.   }
17.   for (int y=0; y<dim; y++) {
18.     stroke(0, 255, 0, 55+(sin(frameCount*0.05 - y)+1)*100);
    
19.     int rY = rowSize/2 + y*rowSize;
20.     line(0, rY, width, rY);
21.   }
22.   stroke(0, 255, 0);
23.   for (int x=0; x<dim; x++) {
24.     int rX = columnSize/2 + x*columnSize;
25.     line(rX, 0, rX, height);
26.   }
27.   if (glow == null) {
28.     glow = get();
29.     glow.filter(DILATE);
30.     glow.filter(BLUR, 2);
31.   }
32. }
33.  
34. void keyPressed() {
35.   if (key == ' ') { glowOn = !glowOn; }
36. }

That's what I was looking for.Thanks amnon.
