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)	0.6
Frequency	`freq`	1..60	18

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": "scanlineWarp", "params": { "amount": 0.6, "freq": 18 } }

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(){ float w = sin(vUv.y*uFreq + uTime*2.0) * cos(vUv.y*uFreq*0.37 - uTime*1.3); vec2 uv = vec2(fract(vUv.x + w*uAmount*0.2), vUv.y); gl_FragColor = texture2D(uTex, uv); }
