selfBlend

Self Blend

The frame differenced against its own offset copy — edges only.

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
Spread	`spread`	0..0.06	0.015

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": "selfBlend", "params": { "amount": 0.6, "spread": 0.015 } }

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(){ vec4 base = texture2D(uTex, vUv); vec2 off = vec2(uSpread, -uSpread * 0.6); vec3 shifted = texture2D(uTex, fract(vUv + off)).rgb; vec3 diff = abs(base.rgb - shifted); gl_FragColor = vec4(mix(base.rgb, diff, uAmount), base.a); }
