moirePulse

Moiré Pulse

Two concentric ring systems at incommensurate frequencies — hypnotic interference beats that never repeat.

What it reads

Frame-local Reads only the current frame, which makes it the cheapest kind to stack and safe to render into a Conjure window at any size.

Parameters

param	key	range	default
Amount	`amount`	0..1 (rendered to 2)	0.8
Density	`density`	0.5..3	1.5
Speed	`speed`	0..4	1.5

The renderer widens amount past its declared maximum by 2× before it reaches the shader, because most shader bodies were tuned against a muted top end. The rendered figure is the bound that actually arrives.

Defaults as a layer

{ "effectId": "moirePulse", "params": { "amount": 0.8, "density": 1.5, "speed": 1.5 } }

GLSL fragment shader

The effect's own code. The uniforms and helpers above it — uTex, uFeedback, the depth proxy, the frame ring, depthAt(), timeAt() — are the same header every Ether-MOSH shader opens with, and are documented once on the registry rather than reprinted on all 143 pages.

void main(){ vec2 p = vUv - 0.5; float rr = length(p) * 28.0 * uDensity; float t = uTime * uSpeed; float ring1 = sin(rr - t * 2.0); float ring2 = sin(rr * 1.0847 + t * 1.73); float moire = ring1 * ring2 * 0.5 + 0.5; moire = pow(moire, 1.8); float hue = moire * 0.5 + t * 0.08 + length(p) * 0.4; vec3 col = hsv2rgb(vec3(fract(hue), 0.95, 0.5 + 0.5 * moire)); vec4 c = texture2D(uTex, vUv); gl_FragColor = vec4(mix(c.rgb, c.rgb * 0.2 + col * 1.6, moire * uAmount), c.a); }
