Middleware Spaziale Enterprise: OpenXR 1.1, WebXR e OpenUSD
Livello di astrazione ad alte prestazioni che collega hardware XR proprietario, pipeline neurali e formati CAD/BIM tramite OpenXR, WebXR e OpenUSD.
Real-Time Spatial Computing & 3D Gaussian Splatting Architecture Modes
- 01. 3D Gaussian Splatting Pipeline: Rappresentazione volumetrica esplicita 3D che parametrizza milioni di gaussiane con posizione, covarianza anisotropa, opacità e armoniche sferiche a oltre 60 FPS. (Flow: Structure-from-Motion Point Cloud -> Covariance Matrix Optimization -> Spherical Harmonics (Degree 3) -> Tile-Based Rasterization (> 60 FPS))
- 02. Spatial Hypervisor & Multi-Tenant Mesh: Virtualizzazione GPU bare-metal che suddivide l'hardware in slice spaziali deterministiche con isolamento al microsecondo e memoria condivisa zero-copy. (Flow: Bare-Metal Host GPU -> SR-IOV vGPU Partitioning -> Zero-Copy Unified Memory IPC -> Motion-to-Photon Sync (< 4.2 ms))
- 03. Omnimodal Stereo Localization & SLAM: Odometria visivo-inerziale stereoscopica e SLAM neurale continuo con campi di distanza troncata (TSDF) e ripetibilità inferiore a 2,5 mm. (Flow: Binocular Stereo Rig + RGB-D -> Disparity Cost Volume -> Visual-Inertial Bundle Adjustment -> Metric Spatial Anchor (< 2.5 mm))
- 04. Low-Latency Spatial Telecom Streaming: Network slicing 5G URLLC unito a codifica foveated guidata dallo sguardo e WebRTC deterministico, per streaming volumetrico 6DoF sotto i 15 ms. (Flow: 6DoF Head Pose -> 5G URLLC Slicing -> Gaze-Contingent Foveated Tile Encoding -> WebRTC Jitter Buffer (< 15 ms))
End-to-End Spatial Computing Topology Layers
- Livello 01: Acquisizione Omnimodale e Ingress di Realtà: Telecamere stereo binoculari sincronizzate in hardware, LiDAR multi-eco, array di profondità ToF e audio spaziale Ambisonics con timestamp IEEE 1588 PTP.
- Livello 02: Ricostruzione Volumetrica e Motore di Radianza: Ottimizzazione GPU di 3D Gaussian Splatting, potatura dinamica, calcolo delle armoniche sferiche e generazione OpenUSD.
- Livello 03: Hypervisor Spaziale Distribuito e Coordinazione: Slicing temporale vGPU bare-metal, grafi di scena multi-tenant isolati in memoria, fisica real-time e bridging OpenXR 1.1.
- Livello 04: Streaming Edge e Telepresenza Olografica: Reti 5G URLLC e Wi-Fi 7, compressione foveated basata sullo sguardo, WebRTC deterministico e rendering sub-4,2 ms su HMD.
Spatial Performance & Latency Benchmarks: > 60 FPS (Volumetric Splat Rendering) | < 4.2 ms (Motion-to-Photon Latency) | < 2.5 mm (Spatial Anchor Repeatability) | < 15 ms (5G URLLC Holographic Delivery)
