Orbitour | Jin Gao

Orbitour turns real estate, venues, museums, hotels, and tourism destinations into immersive 3D walkthroughs you can explore freely — no static panoramas, no point-to-point jumps. The centerpiece is an always-on AI tour guide: an agent that greets visitors, answers their questions, and tells the story behind every point of interest, 24/7.

As AI agent engineer, I focused on the conversational touring layer — the AI guide and the real-time, voice-and-video tour experience that sits on top of the 3D scene.

AI Tour Guide for Every Space

An always-on agent turns a passive walkthrough into a conversation. It meets visitors inside the scene, answers their questions in natural language, and narrates each point of interest on demand.

Conversational Guidance: Visitors ask questions out loud and get grounded answers about the space, its features, and its story.
Spatially Aware: The agent ties its narration to the visitor's location and the points of interest around them.
Always Available: Handles inquiries 24/7, so every visitor gets a guided experience without scheduling.
Hand-off to Live Tours: When a visitor wants a human, a real-time LiveKit video call connects them to a host who walks the space with them.

Live Guided Virtual Tours

When automated answers aren't enough, visitors can join a live, real-time tour. Built on LiveKit, the platform supports both an agent role and a customer role, with Photon-based avatar sync so participants share presence inside the same 3D space. A host can walk visitors through the space, answer questions, and help them make decisions on the spot.

Platform Capabilities

Beneath the conversational layer, Orbitour is a full 3D touring platform rendered with Three.js and 3D Gaussian Splatting.

Photorealistic 3D Walkthroughs: Continuous, free movement through captured spaces using 3D Gaussian Splatting (Spark and LCC formats).
Waypoint Tours: Smooth Catmull-Rom camera paths with pause/resume and named stops, including a carousel toolbar mode.
Hotspots & 3D Media Planes: Interactive markers and in-world image/video/audio planes placed directly in the scene.
AI Virtual Staging: Fill empty spaces with virtual furniture so audiences can picture the possibilities.
One-Click Fly-Through Videos: Auto-generated cinematic clips for marketing and social, straight from the 3D scene.
In-Browser 3D Editor: An edit mode with hierarchy and content panels, transform gizmos, and JSON import/export for authoring tours.
