Ryoji

The Ryoji node recursively subdivides the frame into a grid of black and white cells, in the stark data-visualization style of Ryoji Ikeda. Rows scroll independently, giving a restless, flickering data-panel look.

• One texture output; two optional texture inputs (domain warp and composite)
• Subdivision, contrast, fill, and scroll controls
• Found in nerdGRAPH under Generators as Ryoji

The image on the right is the example patch itself — drag and drop it onto the app (or load it with File → Load) to open the full graph.

Inputs and outputs

Parameters

Opacity, Blend Mode, ALPHA, Invert Alpha, Threshold Min / Threshold Max — the standard operator header; see Perlin Noise for details.

Structure

• Split A / Split B / Split C (1–16, defaults 8 / 3 / 5) — the subdivision counts at each recursion level. Together they set how fine the grid gets.
• Split Probability (0–1, default 0.5) — the chance a cell subdivides further.
• Center Density (0–1, default 0) — biases subdivision so cells get smaller toward the center.
• Padding (default 0.003) — the gap around each cell.

Appearance

• Contrast (0–1, default 0.75) and Fill Ratio (0–1, default 0.5) — the balance and hardness of black vs. white cells.
• Highlight and Highlight Color — a bright accent on a fraction of cells.
• Mix Input / Light Input (0–1) — blend the connected Input texture into the cells' fill and lighting.

Scroll

• Scroll Speed (0–5, default 0.5), Scroll Probability (0–1, default 0.5), Scroll Offset — how many rows scroll, how fast, and their starting phase.
• Speed (0–5, default 1) — overall animation rate, compounding with the global animation speed.

Every slider has a per-parameter animation bar, so any of these can be animated, audio-driven, or MIDI-mapped — see Parameters and Controls.

Troubleshooting

Grid doesn't scroll — raise Scroll Probability (so some rows are eligible) and Scroll Speed, and make sure global animation is playing.

Too uniform — raise Split Probability and vary Split A/B/C for a less regular grid.
