TouchDesigner Tutorial: Create a Procedural Layered Grid with POPs (Easy)

In this TouchDesigner tutorial, we build a complex, procedural, layered composition that blends 2D glitch aesthetics with 3D depth. We use the POP family to convert texture data into high-density architectural grids, creating a system that behaves like a living data organism. You will learn to structure multi-layered geometry using Top to POP, Copy POP, and LFO CHOP scripts to automate motion across five distinct layers. Download the fully Project File on Patreon.

*TIMECODE*
00:00 *Tutorial Introduction*
Welcome to the Superfast TouchDesigner tutorial series.
We start by building a modern data-driven glyph dither effect.

00:30 *Network Overview*
Analyze the three main layers driving the rectangular glyphs and circles.
The system uses noise to fill negative space with organic shapes.

01:09 *Setting Global Scale*
Create a Constant CHOP to define the global grid proportions.
This ensures all symbols and shapes remain perfectly aligned throughout.

01:35 *Building First Layer*
Create a Noise TOP with nearest pixel sampling for hard edges.
Connect the texture to a TOP to POP to convert pixels into points.

03:07 *Instancing Rectangles*
Use a Copy POP to place rectangles on every valid point of the grid.
Add a Lookup Texture POP with a Ramp TOP for custom color mapping.

04:32 *Creating Inverse Circles*
Reference the original noise and use a Level TOP to invert the pattern.
Replace the rectangles with Circle POPs to fill the negative gaps.

05:25 *Adding Detail Crosses*
Generate a third layer of cross-shaped glyphs for fine detail pass.
Merge multiple Rectangle POPs and use a Transform POP for scale.

06:47 *Final Rendering Setup*
Configure an Orthographic Camera and Render TOP for a flat graphic look.
Set the pixel format to 32-bit float for high-quality black and white.
