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
Angle	`angle`	0..3.14159	0.5

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": "frameSmear", "params": { "amount": 0.5, "angle": 0.5 } }

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(){ // Half turn — a full 2*PI sweep returns to its own starting direction. vec2 dir = vec2(cos(uAngle), sin(uAngle)); vec4 acc = vec4(0.0); float w = 0.0; for (int i=0;i<8;i++){ float t = float(i)/8.0; float k = 1.0 - t; acc += texture2D(uTex, vUv - dir*t*uAmount*0.16) * k; w += k; } gl_FragColor = acc/w; }
