xrblocks

Build immersive XR web apps with spatial interactions

Builds cross-platform XR web applications with hand tracking, spatial UI, depth sensing, and world understanding. Eliminates complex WebXR boilerplate, manual gesture wiring, and headset-only testing through a desktop simulator. Guides agents through app scaffolding, interactions, AI integration, debugging, and SDK contributions with verified patterns.

Frequently Asked Questions

FAQPage Schema

How to install XR Blocks?▼

Run `npx skills add google/xrblocks --all -g -y` in your terminal to install all skills in this suite globally.

What is XR Blocks used for?▼

XR Blocks is a JavaScript SDK for rapidly prototyping XR and AI experiences on the web, built on three.js. It targets WebXR headsets like Galaxy XR and includes a desktop simulator for development.

Can I test XR apps without a headset?▼

Yes. XR Blocks ships a desktop simulator that runs the same code in a normal Chrome browser, simulating hands, depth, planes, and controllers.

Does XR Blocks support hand and head gestures?▼

Yes. It provides built-in pinch, fist, thumbs-up, and point detection plus nod and shake head gestures, with support for custom TensorFlow Lite recognizers.

Can I add Gemini AI to my XR app?▼

Yes. The SDK integrates Gemini for text queries, live voice and video conversations, image generation, and scene-grounded responses via the xb.ai facade.
