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
Mix	`amount`	0..1 (rendered to 2)	0.8
Range	`range`	0..1	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": "thermal", "params": { "amount": 0.8, "range": 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(){ vec4 c = texture2D(uTex, vUv); // Range narrows or widens the temperature window. float l = clamp((dot(c.rgb, vec3(0.299,0.587,0.114)) - 0.5) * mix(0.45, 2.6, uRange) + 0.5, 0.0, 1.0); vec3 cold = vec3(0.05,0.0,0.4); vec3 mid = vec3(0.95,0.2,0.6); vec3 hot = vec3(1.0,1.0,0.4); vec3 t = mix(cold, mid, smoothstep(0.0,0.5,l)); t = mix(t, hot, smoothstep(0.5,1.0,l)); gl_FragColor = vec4(mix(c.rgb, t, uAmount), c.a); }
