About Voronoi Pulse Cells

Voronoi Pulse Cells divides the screen into an organic mosaic of irregularly shaped cells using Voronoi tessellation, with each cell pulsing and shifting color independently based on audio frequency data. The cell boundaries glow with energy on beat hits, and the cell centers drift slowly to reshape the tessellation over time. The result is a living stained-glass window that reorganizes itself to the rhythm of your music. The organic, cellular appearance of Voronoi tessellation gives this effect a distinctly biological feel. Cells appear to divide and merge, grow and shrink, like a living tissue observed under a microscope. Bass frequencies cause cells to bloat and merge while high frequencies cause them to fragment into smaller, more numerous cells. The constant reshaping creates a fascinating interplay between geometric structure and organic motion. Voronoi Pulse Cells offers a unique aesthetic that sits between the mathematical precision of geometric visualizers and the organic flow of fluid effects. The clean cell boundaries provide visual structure while the irregular shapes and shifting topology keep the eye engaged with unexpected transformations.

How it works

Voronoi tessellation is computed in the fragment shader using the standard distance-to-nearest-seed-point algorithm. Seed points are initialized with seeded positions and drift according to audio-modulated velocity vectors. Each cell is assigned a frequency band, and its fill color intensity is driven by that band's energy. Cell edges are detected by comparing distances to the nearest and second-nearest seed points, with edge glow intensity tied to overall RMS energy. The number of seed points (and therefore cells) is dynamically adjusted based on spectral complexity -- more complex audio produces more, smaller cells.

Frequently Asked Questions

How many cells are displayed?+
The cell count dynamically adjusts between 12 and 64 based on spectral complexity. You can also set a fixed count or adjust the range in the effect settings.
Can I customize the cell colors?+
Yes. Cells can use a single color with intensity variation, a palette where each cell gets a different color, or spectral mapping where cell color reflects its assigned frequency band.
Does the tessellation pattern change over time?+
Yes. The Voronoi seed points drift continuously based on audio forces, causing the cell boundaries to reshape constantly. No two moments have the same tessellation pattern.
