OpenHuman Realistic Render Engine

A pure WebGL 2.0 digital human render engine with zero runtime dependencies.

Quick Start

npm install
npm run dev
# Open http://localhost:8080/demo/index.html

Development

npm run dev
# Main demo: http://localhost:8080/demo/index.html
# Streaming demo: http://localhost:8080/demo/streaming.html

Production Build

npm run build
npm run preview

Architecture

• src/core/ — WebGL2 context, state cache, buffer/shader/render-target wrappers
• src/math/ — Vec2/3/4, Mat3/4, Quat, DualQuat (no external math lib)
• src/renderer/ — ForwardRenderer (functional), Deferred/PostProcess/ShadowMap (scaffolded)
• src/asset/ — glTF 2.0 loader
• src/scene/ — Node, Camera, Light, Character
• src/sdk/ — Public OpenHuman API

Demo

Open /demo/index.html in a browser (served from public/demo).

The demos now run through Vite with vanilla JavaScript entry modules:

• public/demo/index.html loads demo/index.js
• public/demo/streaming.html loads demo/streaming.js

Constraints

• Zero runtime dependencies
• WebGL 2.0 primary target
• Performance-first: no allocations in hot loops, all GL state via StateCache
