Enterprise Spatial Middleware: OpenXR 1.1, WebXR & Universal Scene Description
High-performance abstraction layer bridging proprietary XR hardware, neural rendering pipelines, and industrial CAD/BIM formats through standard OpenXR, WebXR, and OpenUSD APIs.
Real-Time Spatial Computing & 3D Gaussian Splatting Architecture Modes
- 01. 3D Gaussian Splatting Pipeline: Explicit 3D volumetric representation parameterizing millions of 3D Gaussians with position, anisotropic covariance, opacity, and view-dependent spherical harmonics, rendered via differentiable tile-based rasterization at 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: Bare-metal GPU virtualization partitioning hardware into deterministic spatial execution slices with microsecond context isolation and zero-copy framebuffer sharing for multi-user WebXR sessions. (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: Tightly-coupled stereoscopic visual-inertial odometry and dense neural SLAM constructing continuous truncated signed distance fields (TSDF) with sub-2.5 mm spatial anchor repeatability. (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: 5G URLLC carrier network slicing combined with foveated gaze-predicted tile video encoding and deterministic WebRTC data channels, delivering 6DoF volumetric interactive streams under 15 ms end-to-end network latency. (Flow: 6DoF Head Pose -> 5G URLLC Slicing -> Gaze-Contingent Foveated Tile Encoding -> WebRTC Jitter Buffer (< 15 ms))
End-to-End Spatial Computing Topology Layers
- Layer 01: Omnimodal Capture & Reality Ingress: Hardware-synchronized binocular stereo cameras, multi-echo LiDAR scanners, time-of-flight depth arrays, and Ambisonics spatial audio arrays timestamped via IEEE 1588 PTP.
- Layer 02: Volumetric Reconstruction & Radiance Core: GPU-accelerated 3D Gaussian Splatting optimization, dynamic point-cloud pruning, view-dependent spherical harmonics fitting, and OpenUSD stage asset generation.
- Layer 03: Distributed Spatial Hypervisor & Coordination: Bare-metal vGPU temporal slicing, memory-isolated multi-tenant scene graphs, real-time physics collision detection, and OpenXR 1.1 runtime bridging.
- Layer 04: Edge Streaming & Holographic Telepresence: 5G URLLC and Wi-Fi 7 network pipelines, gaze-contingent foveated video compression, deterministic WebRTC data channels, and sub-4.2 ms motion-to-photon presentation on HMDs.
