Building a High-Performance WebXR Shooter with Gemini XR Blocks

I recently ran a GDG Build with AI workshop where we built a high-performance WebXR shooter using Gemini XR Blocks and Three.js.

The project explores:

XR fundamentals for beginners
Prompt-driven XR development
Treadmill locomotion for comfort
Object pooling for performance
Diegetic UI design
