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
Scale	`scale`	1..16	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": "displacement", "params": { "amount": 0.5, "scale": 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(){ // Speed folded into a constant: a third param is unreachable from the pad, // which binds X to params[0] and Y to params[1]. vec2 p = vUv*uScale + uTime*0.12; float n1 = noise(p); float n2 = noise(p + vec2(5.2, 1.3)); vec2 grad = vec2(noise(p+vec2(0.01,0.0))-n1, noise(p+vec2(0.0,0.01))-n2); vec2 curl = vec2(-grad.y, grad.x); gl_FragColor = texture2D(uTex, vUv + curl*uAmount*4.0); }
