Generative Type Letterforms
toxi_openframeworks · GenerativeTypeLetterforms
Letterforms assembled from a 9×9 stroke grid alphabet (A–Z subset), then modulated by a parametric function (bar widths and stroke positions follow `a * sin(b*x + c)` style curves) and optionally recursively subdivided into smaller marks.
Gray-Scott Reaction-Diffusion
toxi_openframeworks · ReactionDiffusionGS
The canonical two-species Gray-Scott reaction-diffusion model on a periodic square grid: dU/dt = Du*lap(U) - U*V^2 + F*(1-U), dV/dt = Dv*lap(V) + U*V^2 - (F+k)*V.
Median-Cut Color Quantizer
toxi_openframeworks · ColorQuantizer
Heckbert's 1982 median-cut color quantization applied to an evolving procedural gradient + low-resolution noise wash.
Pixel Sort (Glitch Art)
toxi_openframeworks · PixelSort
Per-row pixel sorting à la Kim Asendorf's `ASDFPixelSort` and Karsten Schmidt's own glitch-art Processing sketches.
Sound-Reactive Particle Field (Synthetic Audio)
toxi_openframeworks · SoundReactiveField
Particles advected by a force field whose horizontal component is driven by a synthetic audio signal: a chain of N sinusoids at different frequencies/amplitudes (the 'audio'), with the audio's instantaneous value plus its time derivative ('beat onset') driving the field.
Verlet Particle-Spring Network
toxi_openframeworks · ParticleSpring2D
A Verlet-integrated particle network connected to its k-nearest neighbours by Hooke's-law springs.
Voronoi Tessellation with Lloyd Relaxation
toxi_openframeworks · VoronoiRelaxation
Lloyd's algorithm applied to a jittered point cloud: each seed is replaced with the centroid of its Voronoi cell, repeatedly, producing ever-more-uniform polygonal cells.
