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
Sharpness	`sharpness`	0.3..3	1.2

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": "zoomPunch", "params": { "amount": 0.5, "sharpness": 1.2 } }

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(){ vec2 uv = vUv - 0.5; float punch = pow(clamp(uPulse, 0.0, 1.0), uSharpness) * uAmount; uv *= 1.0 - punch * 0.4; uv += 0.5; gl_FragColor = texture2D(uTex, clamp(uv, 0.0, 1.0)); }
