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
Speed	`speed`	0..4	1

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": "chromaPulse", "params": { "amount": 0.6, "speed": 1 } }

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 t = uTime * uSpeed; // Let the channels visibly separate at the upper end, without more samples. float reach = uAmount * (1.0 + 1.5 * smoothstep(0.6, 2.0, uAmount)) * 0.03; vec2 dr = vec2(cos(t), sin(t)) * reach; vec2 dg = vec2(cos(t*1.37+2.0), sin(t*1.37+2.0)) * reach; vec2 db = vec2(cos(t*0.73+4.0), sin(t*0.73+4.0)) * reach; float r = texture2D(uTex, vUv+dr).r; float g = texture2D(uTex, vUv+dg).g; float b = texture2D(uTex, vUv+db).b; // Alpha rides the green channel's own breathing offset. gl_FragColor = vec4(r,g,b,texture2D(uTex, vUv+dg).a); }
