Dude this is awesome!

3

cool. Not big fan of the cube object but the lines chaos is nice. Maybe a frontal view would do?

4

Just had a though, I think it would be cool if that lattice had an emission shader applied to it. :slight_smile:

5

First picture has emission applied to lines

6

Interesting result! It’s possible to share the python code? I think can be very useful to “starters” as me, if it’s not much complicated.

norm. try Sverchok for this kind of art

First line: Well, how hard could it be?
Last line: :spin:

Very nice concept.

code must be separated like this

Yes, i figured out the indentation. I had to add from math import sqrt…strangely the console said sqrt is not defined; same as variables one and two (from bpy.context.object.name = “Sphere_” + “{}”.format(one) + “_{}”.format(two) ; i don’t understand much the second part of this line).
My problem now is that i am very rusty with trigonometry :frowning: anyway thank you for sharing the code.

When I copy code form Eclipse and paste in Blender Python console - I did not get any error…

You can try:
line 10 - bpy.context.object.name = “Sphere_” + “0” + “_{}”.format(two)
and
before sqrt and pow put math. like
garums_x_y = math.sqrt(math.pow(x2 - x1,2) + math.pow(y2 - y1 ,2))
garums = math.sqrt(math.pow(garums_x_y,2) + math.pow(z2 - z1,2))
