Worlds in Action Hack [02]: SIGGRAPH LA

​Right before #SIGGRAPH2026, founders, researchers, engineers, VFX artists, game developers, and spatial computing pioneers will come together in Los Angeles to prototype the next generation of AI-native 3D experiences.

​If you’re building the future of:

• ​AI-generated 3D worlds
• ​Spatial interfaces
• ​Interactive agents
• ​XR workflows
• ​Simulation systems
• ​Generative environments
• ​Human-AI interaction in 3D space

​…this is your Hack!

​Create immersive systems powered by:

• ​World Models
• ​Spatial AI
• ​Gaussian Splats
• ​3D GenAI pipelines
• ​Multi-agent environments
• ​WebXR and cross-platform deployment
• ​AI-assisted creative workflows

​Ship prototypes, experiment fast, collaborate with top builders, and demo your work live.

• ​Hands-on prototyping
• ​Mentorship by top professionals
• ​Expert-led workshops
• ​Free credits and workflow kits

• ​World Model APIs and Credits
• ​Open Source World Model kits - ​Unity/Unreal/WebXR
• ​WebSpatial cross-platform deployment
• ​AI-assisted workflows via MCP connectors - WebXR, Blender, and more
• ​Gaussian splat interaction and collision systems
• ​VFX, 3D GenAI, and reconstruction pipelines
• ​Mentors and technical support

​​To get up to speed, sign up for the pre-hack workshops:

• Info Session, Ideation & Team Formation

• ​$10,000 in prizes
