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)	0.5
Frequency	`freq`	4..80	30

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": "ripple", "params": { "amount": 0.5, "freq": 30 } }

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 r = length(p); // A gentle low end, with broad folds at full strength; zero stays identity. float reach = uAmount * (1.0 + 1.5 * smoothstep(0.6, 2.0, uAmount)); float w = sin(r*uFreq - uTime*4.0) * reach * 0.04; gl_FragColor = texture2D(uTex, vUv + normalize(p+0.0001)*w); }
