How Pendulum Physics Drive Every Line

Fruuit Coctaiil simulates authentic harmonograph mechanics using coordinate-based pendulum systems. Each axis receives independent frequency and damping values represented as three-value arrays that control amplitude, frequency, and phase offset.

The Studio mode runs live visualization where pendulum calculations update in real-time at 50 frames per second. Lateral pendulums X₁ and X₂ control horizontal motion while Y₁ and Y₂ govern vertical trajectory. When these four pendulums interact with slightly detuned frequencies, interference patterns emerge as flowing ribbons and orbital shapes.

Linear damping simulates friction over duration, gradually pulling the pattern toward equilibrium. This creates the characteristic spiral convergence visible in artworks like Violet Orbit. Parameter precision extends to three decimal places enabling microscopic frequency adjustments that dramatically alter final geometry.

Complete Harmonograph Toolkit

Professional-grade controls for mathematical art generation

Precision Tuning

Adjust four independent pendulums with granular frequency control down to 0.001 increments. Modify amplitude, phase offset, and decay rates through dedicated sliders for surgical pattern manipulation.

Aurora Gradient System

Map pendulum motion to flowing color gradients that transition from cyan through purple to yellow. Customize gradient stops or select from predefined palettes designed for harmonograph visualization.

Classic Presets

Instant access to Rose petal formations, Lissajous ribbons, Spiral vortices, and Knot lattices. Each preset loads authenticated parameter sets from historical harmonograph families.

Surprise Generator

Randomize all pendulum parameters within aesthetic constraints to discover unexpected geometries. Algorithm ensures generated patterns maintain visual coherence while exploring parameter space.

Gallery Archive

Save unlimited harmonograph artworks with embedded metadata including full pendulum coordinates, palette selection, sample count, and generation date. Reload any saved configuration instantly.

Export Pipeline

Render finished patterns at high resolution for printing or sharing. Export wireframe data as vector paths for integration with professional design tools.

Pattern Creation Workflow

Studio Operations

  • Select preset family or start with blank pendulum configuration
  • Adjust X-axis pendulums using frequency and damping sliders
  • Fine-tune Y-axis parameters to create perpendicular motion interference
  • Watch live preview update in real-time as values change
  • Modify sample count to increase line density and smoothness
  • Apply color palette gradient to visualize motion trajectory
  • Save artwork with automatically embedded technical parameters

Advanced Customization

  • Rotate entire coordinate system to explore pattern from different angles
  • Layer multiple damping curves for complex convergence behavior
  • Extend duration up to 120 seconds for elaborate trailing effects
  • Export individual pendulum motion paths as separate objects
  • Apply post-generation blur and glow effects to wireframe
  • Create animation sequences by interpolating between saved states
  • Compare multiple parameter sets side-by-side in gallery view

About The Physics Engine

Fruuit Coctaiil implements numerically stable pendulum integration using fourth-order Runge-Kutta methods. This ensures pattern accuracy even at high sample counts and extended durations without drift accumulation or numerical instability.
