TriDComm Integration Guide: APIs, SDKs, and Best Practices
Overview
TriDComm is a fictional (assumed) platform for real-time 3D data communication across AR/VR and collaborative applications. This guide assumes typical features: REST and WebSocket APIs, SDKs for major platforms, real-time synchronization, security, and performance tuning.
Supported Integrations
- Web: JavaScript SDK (browser, WebXR)
- Mobile: iOS (Swift), Android (Kotlin)
- Desktop/Engine: Unity (C#), Unreal (C++)
- Backend: Server SDKs (Node.js, Python, Go) for signaling, session management, and media relay
Authentication & Authorization
- API keys: Short-lived keys for server-to-server operations.
- OAuth 2.0 / JWT: User authentication; issue JWTs from your auth server for client SDKs.
- Scopes & Roles: Enforce least privilege — separate scopes for read, write, admin, and realtime-publish.
Core APIs
- REST API
- Session management: create/update/delete sessions, list participants.
- Asset management: upload, list, version 3D assets (gltf, usdz).
- Permissions: set access control on sessions/assets.
- Realtime API (WebSocket/UDP)
- State sync: transform, pose, animation updates.
- Event channels: chat, commands, presence.
- Binary channels: mesh/point-cloud deltas, compressed geometry.
- Signaling
- SDP exchange for peer connections (if using P2P).
- TURN/STUN configuration for NAT traversal.
- Media Relay
- Optional SFU for low-latency multi-party mesh distribution.
- Adaptive bitrate and selective forwarding for heavy geometry streams.
SDK Usage Patterns
- Client: Connect to signaling via REST to join session, then open realtime channel with JWT. Subscribe to entity updates and apply interpolation/extrapolation for smooth motion.
- Server: Validate tokens, manage session lifecycle, persist authoritative state, optionally run server-side physics or reconciliation.
- Unity/Unreal: Use native serializers for transforms; offload heavy mesh processing to worker threads; use GPU-friendly buffers for streamed geometry.
Data Formats & Serialization
- Transforms: Compact binary (position float32 x3, quaternion float32 x4, timestamp uint64).
- Scene Graph: Node IDs + parent IDs, minimal metadata.
- Geometry Deltas: DRACO-compressed glTF deltas or custom binary diff format.
- Messages: Protobuf or MessagePack for low overhead and schema evolution.
Performance Best Practices
- Delta updates: Send only changes; rate-limit high-frequency channels.
- LOD & Culling: Stream low-detail LODs first; progressively refine.
- Compression: Use DRACO for meshes, Opus for audio, quantized floats for poses.
- Batching: Aggregate small updates into single frames.
- Network: Prefer UDP-like protocols or QUIC for lower latency; fallback to WebSocket when necessary.
Security Best Practices
- Short-lived tokens for clients; rotate server keys frequently.
- Encryption: TLS for signaling and DTLS/SRTP for media/realtime channels.
- Input validation: Sanitize incoming messages, enforce size limits.
- Rate limiting & quotas to mitigate abuse and runaway clients.
Error Handling & Reconciliation
- State snapshots: Periodic authoritative snapshots to correct drift.
- Conflict resolution: Last-writer-wins for non-critical fields; server arbitration for authoritative state.
- Reconnect strategy: Exponential backoff, resume tokens to recover missed updates.
Testing & Monitoring
- Simulate load: Tools to emulate hundreds/thousands of clients with varied network profiles.
- Metrics: Latency, jitter, packet loss, update rates, CPU/GPU load.
- Logging: Structured logs for session events, errors, and security incidents.
- SLOs: Define acceptable latency and sync accuracy targets.
Deployment Patterns
- Hybrid: P2P for small groups, SFU/relay for larger sessions.
- Edge servers: Place relays near users for lower latency.
- Autoscaling: Scale relays and processing workers based on active sessions and bandwidth.
Example Integration Flow (high-level)
- Server creates session via REST.
- Client requests join, authenticates, receives JWT.
- Client uploads/requests assets, downloads initial
