I like an example story if coding by John Maeda, where he fillled up his computer monitor screen with infinite text. In the old days, printing text into screen that gives you a stream of text is a big thing.

You could think of “HELLO WORLD” as a piece of string text data that gets printed out to make a pattern that fills up your screen infinitely. That’s certainly one starting idea.

But in 3D, we are not limited to text. You can use polygon face and particles and instancing, and you have unlimited 3D space in XYZ..

You could also think of nodes that generates an array of objects or continuously random stamping of instance of mesh as a print.

Finally I think, the act of replacing polygon face with another polygon face with more details would be another example.

The ultimate is probably the idea of filling up VOXEL 3D and to be able to paint or erase voxel grid, which I have not explored, but maybe you can try.

If you are more into Shaders, you can also try Eevee or Cycles nodes that generate random stamping from a single texture to generate organic pattern. I think Erin XYZ shader is one great example.

So that’s today’s lecture on stamping and generating mesh that is I think the equivalent of “PRINTING HELLO WORLD” in Nodes.
