LUMEN-1 · a cinematic scene language

Cinema, written
in code.

zLumen turns pure source text into photoreal 3D video — faces that breathe, blink and speak, lit by online HDRIs and skinned with real subsurface-scattering shaders. No 3D app. No downloads. Just code.

the origin story

Built with Z.AI GLM 5.3 Flash

Not assisted. Not pair-programmed. Authored. Every token of the lexer, every grammar rule of the parser, every viseme blend, every line of GLSL that scatters light through virtual skin — written end-to-end by GLM 5.3 Flash, Z.AI’s flagship coding model, in one continuous conversation. A language design, a rendering engine and a photoreal face pilot, from first prompt to shipping product.

Lexer

tokenizer with durations, hex colors, vectors, diagnostics

Parser

recursive-descent grammar → cinematic scene AST

Visemes

text → ARKit visemes with coarticulation & pauses

Engine

Three.js runtime, HDR IBL, deterministic timeline

Skin shader

GLSL subsurface scattering, pores, dual specular

A language, not a config

LUMEN-1 is a declarative cinematic scene language — camera paths, lights, emotion curves and speech compile from plain source text.

Photoreal skin shaders

Per-channel wrapped subsurface scattering, procedural pore relief, oily clearcoat and peach-fuzz sheen — pure GLSL, injected live.

Online textures & assets

Models, HDRIs and detail maps stream straight from the web through a CORS-safe relay. Zero downloads to start creating.

One-click video export

The timeline is a pure function of time. Hit export and the studio records a deterministic 12 Mbps VP9 cut in your browser.
