Platform Overview

YUNA forDevelopers

A deep dive into YUNA's architecture, upcoming features, and the future of AI-powered virtual characters. Built for creators, extensible for developers.

Architecture Overview

YUNA is built on a modular architecture designed for performance and extensibility.

Live2D / 3D Rendering

WebGL-based rendering pipeline with PIXI.js for Live2D and Three.js integration planned for 3D models. 60+ FPS performance with physics simulation.

Adapter Pattern

Unified adapter interface for model control. Switch between Live2D and 3D backends without changing application logic.

Profile System

JSON-based configuration storage for expressions, parameters, parts, and voice settings. Full export/import support.

Local-First Storage

All data stored in browser localStorage. Zero server dependency for core features. Optional cloud sync planned.

architecture.ts
// YUKI Core Architecture
interface YukiConfig {
  model: ModelAdapter;      // Live2D or 3D adapter
  personality: Persona;     // LLM personality config
  voice: VoiceConfig;       // TTS settings
  storage: StorageAdapter;  // Local or cloud
}

// Adapter Pattern for model backends
interface ModelAdapter {
  load(path: string): Promise<void>;
  setParam(id: string, value: number): void;
  applyExpression(name: string): void;
  getParams(): Param[];
  getParts(): Part[];
  exportConfig(): ProjectConfig;
}

// Coming: Plugin system
interface YukiPlugin {
  name: string;
  version: string;
  init(yuki: YukiInstance): void;
  hooks: PluginHooks;
}
Coming Soon

LLM & AI Roadmap

YUNA will support multiple LLM backends for intelligent conversations. Each character can have persistent memory, unique personality traits, and context-aware responses.
