How Virtual Try-On Works
Virtual try-on is AI-powered technology that lets online shoppers see how products look on them in real-time through their webcam. Powered by advanced face tracking and 3D rendering, it runs directly in the browser — no app download, no plugins, just instant visualization.
What Is Virtual Try-On?
Virtual try-on is a breakthrough technology that bridges the gap between online shopping and the in-store experience. Using your device's webcam, it overlays a photorealistic 3D model of a product — like glasses, jewelry, or accessories — onto your live video feed.
The magic happens through a combination of computer vision, AI-powered face tracking, and real-time 3D rendering. By detecting 468 facial landmarks and tracking your head movements with sub-50ms latency, virtual try-on creates an experience that feels natural and responsive.
Unlike traditional AR filters that simply overlay 2D images, TryOn Virtual uses physically-based rendering (PBR) with HDR lighting to ensure products look exactly as they would in real life. The result? Customers can confidently purchase online knowing exactly how the product will look on them.Learn more about the technology.
How the Technology Works
From camera access to photorealistic rendering, here's the four-step process that powers every virtual try-on session.
Camera Access
Secure webcam access is requested once. All processing happens locally on the user's device — no video is ever sent to servers.
AI Face Tracking
468 facial landmarks are detected in real-time using MediaPipe. Our AI tracks head position, rotation, and facial features with 99.2% accuracy.
3D Rendering
Photorealistic PBR (physically-based rendering) with HDR lighting renders the product in Three.js. Products look exactly as they would in real life.
Smart Lighting
Auto-exposure adapts to the user's lighting environment. Whether they're in sunlight or indoors, the product always looks natural.
Why It Matters for E-commerce
Virtual try-on solves the biggest challenge in online retail: the "can't try before you buy" problem. By letting customers visualize products on themselves instantly, merchants see dramatic improvements in conversion, engagement, and customer satisfaction. The results speak for themselves.
