Echo Clones

Copies of you from a moment ago stand beside you, each in its own neon colour: a crowd of past selves.

What it reads

Reads the time ring Looks into the ring of past output frames reaching back about 250ms, which lets it show two moments of the same shot at once.
Depth aware Reads the foreground/background estimate, so it can move the subject independently of the room behind them.

Parameters

param	key	range	default
Clones	`amount`	0..1 (rendered to 2)	0.75
Spread	`spread`	0..1	0.5
Delay	`reach`	0..1	0.5
Hue	`hue`	0..1	0.55
Depth Gate	`gate`	0..1	0.45

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": "echoClones", "params": { "amount": 0.75, "spread": 0.5, "reach": 0.5, "hue": 0.55, "gate": 0.45 } }

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 curTex = texture2D(uTex, vUv); vec3 acc = curTex.rgb; float sp = uSpread * 0.22; // Three clones, one side then the other then further out, each from a later // moment than the last. A clone shows wherever the subject is at its offset // (the depth proxy says where) and wherever that spot changed since then, so a // person standing still still has company and a moving one leaves a wake. vec2 uv1 = vUv + vec2(-sp, 0.0); vec3 p1 = timeAt(uv1, uReach * 0.33); float m1 = max(smoothstep(uGate - 0.15, uGate + 0.15, depthAt(uv1)), 0.8 * smoothstep(0.05, 0.28, length(p1 - texture2D(uTex, uv1).rgb))); vec3 t1 = hsv2rgb(vec3(fract(uHue), 0.85, 1.0)); vec3 g1 = mix(p1, t1 * (0.35 + dot(p1, vec3(0.299, 0.587, 0.114))), 0.7); acc = mix(acc, max(acc, g1), m1 * uAmount * 0.85); vec2 uv2 = vUv + vec2(sp, 0.0); vec3 p2 = timeAt(uv2, uReach * 0.66); float m2 = max(smoothstep(uGate - 0.15, uGate + 0.15, depthAt(uv2)), 0.8 * smoothstep(0.05, 0.28, length(p2 - texture2D(uTex, uv2).rgb))); vec3 t2 = hsv2rgb(vec3(fract(uHue + 0.18), 0.85, 1.0)); vec3 g2 = mix(p2, t2 * (0.35 + dot(p2, vec3(0.299, 0.587, 0.114))), 0.7); acc = mix(acc, max(acc, g2), m2 * uAmount * 0.65); vec2 uv3 = vUv + vec2(-sp * 2.0, 0.0); vec3 p3 = timeAt(uv3, uReach); float m3 = max(smoothstep(uGate - 0.15, uGate + 0.15, depthAt(uv3)), 0.8 * smoothstep(0.05, 0.28, length(p3 - texture2D(uTex, uv3).rgb))); vec3 t3 = hsv2rgb(vec3(fract(uHue + 0.36), 0.85, 1.0)); vec3 g3 = mix(p3, t3 * (0.35 + dot(p3, vec3(0.299, 0.587, 0.114))), 0.7); acc = mix(acc, max(acc, g3), m3 * uAmount * 0.45); gl_FragColor = vec4(acc, curTex.a); }
