Blender + Claude + Polyxd: swapping prompts for sliders to drive a 3D island scene live

sidahuj · x · 2026-10-05

A striking demo: after Claude built a low-poly sunset island in Blender via sidahuj's blender-mcp, the user asked for a control panel instead of typing prompts—time of day, camera, waves, lighthouse and seagulls all became buttons and sliders. The panel is built with Polyxd, an open spec, renderer and verifier for on-demand interfaces: models or programs emit semantic UI JSON, rendered natively in your design system and verified for accessibility, safety and agent operability.
