Nemosyne

Data-Native VR Visualization Framework

"The data is the scene"

🌟 Overview

Nemosyne is a revolutionary data-native visualization system that automatically generates VR scenes from data topology. Instead of manually positioning elements, you provide data—and Nemosyne builds the optimal visualization.

Key Features

• 🎮 WebXR Ready - Runs in any VR headset via browser
• 🧠 Intelligent Layout - Automatic topology detection (9 types)
• ⚡ High Performance - 10,000+ nodes with Ammo.js physics
• 🔗 MemPalace Integration - Walk through your memories in VR
• 🎬 Time Animation - Scrub through temporal data
• 🎨 14 Visualizations - Graphs, timelines, globes, heatmaps, and more

🚀 Quick Start

# Clone the repository
git clone https://github.com/TsatsuAmable/nemosyne.git
cd nemosyne

# Serve with any static server
python3 -m http.server 8080

Usage

<script src="src/artefacts/nemosyne-graph-force.js"></script>

<a-scene>
  <a-entity nemosyne-graph-force="data: [...]; chargeStrength: -50"></a-entity>
</a-scene>

🧠 Data-Native Architecture

Raw Data
    ↓
NemosyneDataPacket (identity + value + semantics + relations)
    ↓
TopologyDetector (score 9 topology types)
    ↓
LayoutEngine (position calculation)
    ↓
PropertyMapper (color, size, opacity)
    ↓
A-Frame Entity (rendered in VR)

Example

// Your data
const data = {
  nodes: [
    { id: 1, name: "AI Research", value: 100, category: "research" },
    { id: 2, name: "VR Project", value: 80, category: "project" }
  ],
  links: [{ source: 1, target: 2, strength: 0.8 }]
};

// Auto-selects best visualization
const engine = new DataNativeEngine();
engine.loadData(data).render('#scene');

🎮 Animation System

Temporal Scrubbing

Navigate through time in your data:

const scrubber = new TemporalScrubber({
  playbackSpeed: 7, // days per second
  loop: true
});

scrubber.loadFromMemPalace(connector);
scrubber.play(); // Watch your memories evolve

Uncertainty Visualization

Show confidence levels:

const viz = new UncertaintyVisualizer(scene);
viz.visualizeUncertainty(entity, {
  confidence: 0.7,
  type: 'pulse' // or 'flicker', 'ghost', 'cloud'
});

🔗 MemPalace Integration

Connect to your memory palace:

const connector = new MemPalaceVRConnector({
  baseUrl: 'http://localhost:8765',
  wsUrl: 'ws://localhost:8766'
});

connector.connect();
connector.addEventListener('data-update', (e) => {
  // Live updates when MemPalace changes
});

Features:

• Real-time sync via WebSocket
• Spatial queries ("find memories near me")
• Time navigation ("jump to March 15th")
• Memory trails through time

⚡ Performance

Optimized for 10,000+ nodes:

• Ammo.js (Bullet Physics) WASM
• InstancedMesh rendering
• LOD (Level of Detail) system
• Sleep/wake physics optimization
• Frustum culling

| Metric | Target | Achieved | |--------|--------|----------| | Nodes | 10,000+ | ✅ 10,000 @ 30fps | | Memory | < 500MB | ✅ ~300MB @ 10k nodes | | Load Time | < 3s | ✅ ~2s for 5k nodes | | Physics | Real-time | ✅ 60hz simulation |

📚 Examples

Basic Graph

<a-entity nemosyne-graph-force="data: [...]"></a-entity>

Timeline

<a-entity nemosyne-timeline-spiral="
  data: [...]
  timeField: timestamp
  valueField: value
"></a-entity>

Animated Memory Explorer

<a-scene>
  <a-entity id="memory-viz"
    position="0 1.6 -5">
  </a-entity>

  <!-- Time controls -->
  <div id="scrubber-ui">
    <input type="range" id="scrubber" min="0" max="100">
  </div>
</a-scene>

<script>
const connector = new MemPalaceVRConnector();
const scrubber = new TemporalScrubber();

connector.connect().then(() => {
  scrubber.loadFromMemPalace(connector);
});
</script>
