Time Displace

Brightness decides how far back in time each pixel is sampled — the frame tears itself across multiple moments.

What it reads

Temporal Samples the previous finished frame, so it accumulates — trails, tunnels and smears build up over time rather than being computed fresh each frame.

Parameters

param	key	range	default
Amount	`amount`	0..1 (rendered to 2)	0.6
Warp	`warp`	0..1	0.4

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": "timeDisplace", "params": { "amount": 0.6, "warp": 0.4 } }

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 cur = texture2D(uTex, vUv); float lum = dot(cur.rgb, vec3(0.299,0.587,0.114)); // Displace the history lookup by luminance, so bright and dark regions // lag by different amounts and the image shears through time. vec2 off = vec2(sin(lum*6.2831 + uTime*0.7), cos(lum*6.2831 - uTime*0.5)) * uWarp * 0.05; vec3 past = texture2D(uFeedback, vUv + off).rgb; float sel = smoothstep(0.25, 0.75, lum); gl_FragColor = vec4(mix(cur.rgb, mix(past, cur.rgb, sel), uAmount), cur.a); }
