Generators

Click + Add Generator Layer to browse all available generators. They are organized into three categories:

Noise Generators

These produce smooth, organic noise patterns.

Perlin — Classic gradient noise. Smooth, natural-looking patterns ideal for terrain and surfaces. Uses an optimized 2D algorithm for fast performance at any scale.

Simplex — Improved noise with fewer directional artifacts than Perlin. Slightly faster and produces rounder features.

FBM — Fractal Brownian Motion. Layers multiple octaves of noise for rich, detailed patterns. Controls: Octaves (detail layers), Persistence (amplitude decay), Lacunarity (frequency scaling), and Noise Type (perlin/simplex/voronoi base).

Ridge — Sharp ridged features created by inverting and squaring each octave. Great for mountain-like or vein patterns.

Billow — Soft, cloud-like patterns created by taking the absolute value of each octave. Produces rounded, puffy shapes.

Voronoi — Cell-based noise that divides space into organic regions. Controls: Distance Metric (euclidean/manhattan/chebyshev), Edge Detect, and Border Width.

3D Voronoi — Advanced cell noise with color palettes, wire overlays, ambient occlusion, and pattern projection. Choose from 11 color palettes (spectrum, ocean, sunset, neon, cyberpunk, etc.) and control color ratio, spread, and saturation.

Caustics — Simulates light refraction through water. Uses wave interference for fast, realistic caustic patterns. Controls: Intensity (line sharpness), Turbulence (wave layers).

Plasma — Classic sine/cosine wave superposition creating flowing, psychedelic patterns. Controls: Complexity (wave layers), Speed (frequency scaling).

Pattern Generators

These produce geometric and structured patterns.

Truchet — Randomized tile-based patterns. Choose from curves, lines, or triangle styles. Control tile size and line thickness.

Tech Pattern — Grid of randomized geometric shapes (circles, crosses, squares, diamonds, rings). Noise-driven density creates organic clustering.

Hexagonal — Honeycomb grid with per-cell fill values and configurable border width.

Spiral — Parametric spiral arms with configurable arm count, twist, and thickness.

Crosshatch — Overlapping line sets at multiple angles. Controls: Angles (line directions), Line Width, Spacing.

Circuit Board — PCB-style traces with edge-connected routing, vias, and IC chip pads. Traces connect between cells with optional dog-leg bends.

Trace Network — Dense interconnected trace patterns with components and junction points.

Herringbone — Classic herringbone tile pattern with configurable line width and tile size.

Quatrefoil — Four-lobed decorative pattern with shape morphing. Use the Shape Morph slider to blend between variations.

Ogee — Pointed arch pattern with configurable line width and intensity.

Polka Dot — Regular dot grid with controllable dot size.

Fret/Meander — Greek key / meander pattern with configurable line width and turbulence for organic variation.

Wang Tiles — Circuit-board inspired tile system using Wang tile edge-matching for seamless connectivity. Features animated data dots flowing along traces, connection pads, and IC-like components. Controls: Scale, Trace Width, Pad Size, Density, Dot Speed, Dot Size, Component Size, Style (angular/rounded).

Ryoji — Recursive cell subdivision inspired by Ryoji Ikeda. Creates grids of black and white cells with scrolling animation. Controls: Split A/B/C (subdivision factors), Split Probability, Padding, Contrast, Fill Ratio, Highlight (probability of accent cells), Highlight Color (color picker with gradient presets), Mix Input (blends other generator output), Scroll Speed/Probability/Offset.

Effects Generators

Rain — Rain drop ripples with refraction distortion. When placed above other layers, the rain distorts the layers below it through the composite texture. When used as the only layer, produces specular ripple highlights on black. Original shader by Zavie / Ctrl-Alt-Test, from the 64kB intro H - Immersion. Controls: Density (ripple count), Speed (animation speed), Distortion (refraction strength), Highlight (specular intensity).

Datastream — Scrolling billowed noise strips inspired by data-flow visualizations. Each strip scrolls independently with per-strip speed variation driven by 3D simplex noise. Accepts a texture input — connect another generator to colorize the strips using the Input Blend parameter. Controls: Density (strip count), Scroll Speed, Noise Amount (per-strip offset randomness), Direction (Horizontal/Vertical/Diagonal), Falloff (inter-strip edge softness), Glow (soft halo), Pulse Width (bar thickness), Fade (trailing edge softness), Mirror (bilateral symmetry), Input Blend (texture input mix).

Special Generators

Reaction Diffusion — Simulated chemical reaction patterns (Turing patterns). Creates organic dots, stripes, and labyrinthine structures that evolve over time.

Gradient — Directional color gradient with configurable angle, repeat, mirror, interpolation type (linear/smooth/cosine/stepped), offset, and width. Used for directional effects and color mapping.

Webcam — Live camera feed as a generator layer. Uses your device camera at up to 1080p. Composite live video with noise generators using blend modes and post effects.
