About

Worlds in Action Hack: SIGGRAPH Edition

Two days in Los Angeles, right before SIGGRAPH 2026, to prototype what's next in AI-native 3D worlds.
The mission: take a world model from idea to working demo.


Build a game, an interactive experience, a spatial agent, or a cinematic AI project - powered by partner kits from World Labs, Tripo, fal.ai, Reactor, ReactVision, XGRIDS, and PICO. Eight tracks are open, spanning storytelling, 3D reconstruction, agentic systems, and more, so bring whatever angle on world models excites you most.

Requirements

Project Requirements

  • Functionality: The project must run consistently on its intended platform and function as shown in the demo video and description.
  • New & Existing: All submissions must be newly created and not previously submitted to any other hackathon. Teams may prepare mockups, scan environments, or fine-tune models beforehand, but no coding is allowed before the event.
  • Third-Party Integrations: Any SDKs, APIs, or data must be used in accordance with licensing terms. Sponsor and Administrator reserve the right to request proof of such authorization or licensure.
  • Category Specific Requirements:

    • Best 3D GenAI Character, Brand or Product Integration - by TRIPO: Must use TRIPO to generate at least one fully embodied character, brand, or product asset integrated into a world model scene.
    • Best 3D Reality Reconstruction Project - by XGRIDS: Must use real-world capture and reconstruction to build the environment, with at least one interactive, responsive element.
    • Best App Running on Emulator - by PICO: Must run on the PICO Emulator, demonstrating at least one productivity, creative, or spatial workflow feature.
    • Best Agentic Spatial System - by PICO: Must implement at least one AI agent with a spatial multi-view interface and use WebSpatial or PICO Spatial SDK.
