Boids Flock (Hodgin Murmuration)
hodgin_iquilezles · BoidsFlock
A 2D flock of boids steered by Craig Reynolds' three classic rules (separation, alignment, cohesion) over a coarse spatial-hash neighbor query.
Fractional Brownian Motion noise
hodgin_iquilezles · FBMNoise
Quilez's canonical fBM: a 2D value-noise base summed over N octaves whose frequency doubles and amplitude is multiplied by G = exp2(-H) per octave.
Magneto Particles (Hodgin Magnetosphere)
hodgin_iquilezles · MagnetoParticles
Particles pulled and pushed by N orbiting magnetic anchors whose charges flip sign over time.
Mulberry32 PRNG (stratified scatter)
hodgin_iquilezles · Mulberry32RNG
Mulberry32 is a tiny 32-bit-state pseudo-random number generator popularised in the demoscene and used pervasively by Quilez and other graphics programmers as the RNG inside procedural sketches.
Saturn Rings (orbital resonance)
hodgin_iquilezles · SaturnRings
Thousands of particles are initialized in an annulus between inner_radius and outer_radius around a central mass, with circular orbital velocities v = sqrt(M/r).
Smooth-Minimum SDF field
hodgin_iquilezles · SmoothMinSDF
Two animated 2D SDF primitives (a moving circle and a translating slab) are blended with Quilez's quadratic-polynomial smooth-minimum and rendered as a scalar field.
Worley / Cellular Noise
hodgin_iquilezles · WorleyNoise
Quilez's classic 2D Worley noise: a unit grid of cells, each containing one pseudo-random feature point placed by a 2D integer hash.
