ATON 3.0 framework

Official ATON website | Telegram open-group | Live examples |

ATON framework - designed, developed and coordinated by B. Fanini (CNR ISPC, ex ITABC) - allows to create scalable, collaborative and cross-device 3D Web-Apps (mobile, desktop and immersive VR) targeting Cultural Heritage exploiting modern web standards, without any installation required for final users. ATON offers:

• Responsive, adaptive and scalable presentation of interactive 3D content (mobile, desktop PCs, museum kiosks, immersive VR devices)
• Real-time collaborative multi-user features (VRoadcast module)
• Immersive VR (WebXR) for 3-DOF and 6-DOF devices
• Multi-resolution for massive 3D datasets through OGC standards
• Multi-touch interfaces
• Spatial UI (3D labels, buttons, etc...) targeting immersive XR sessions
• Built-in navigation modes, including orbit, first-person, device-orientation and immersive VR
• 3D semantic annotations including free-form volumetric shapes
• Fast, real-time 3D queries on visible and semantic graphs and UI nodes
• Built-in front-end ("Hathor") with WYSIWYG rich HTML5 content editor
• Built-in profiler (automatically adapt 3D presentation to different devices)
• Built-in services to access 3D collections and scenes for multiple users via authentication
• Built-in export of 3D scenes/models using different formats (gltf/glb, obj, usd,...) right from the browser
• Event-driven API for fully customizable events (local and synchronous collaborative contexts)
• 360 panoramas and virtual tours
• Physically-Based Rendering (PBR) for advanced materials and custom shaders for complex representations, including latest extensions
• Advanced lighting, including IBL and multiple Light Probes
• Camera/POV transitions, viewpoint handling and custom navigation constraints
• Complex scene-graph manipulation, hierarchical culling, instancing, composition and cascading transformations
• Scalable deployment, from low-cost SBCs (e.g. Raspberry Pi) to large infrastructures
• Multi-temporal (4D) visualization
• Easily extensible through plug&play apps architecture and plugins

The framework also provides a built-in front-end and services based on Node.js for deployment on servers, infrastructures or single-board computers; real-time collaborative multi-user features and support for remote/immersive visual analytics.

Getting started (quick)

1. Install Node.js for your operating system.

2. Install (or update) required modules from main ATON folder by typing:

npm install

3. Deploy ATON main service on local machine simply using:

npm start

4. Open http://localhost:8080 on your browser.
