OpenAI 3D Generation

We do not have a working OpenAI 3D generation graph template yet.

Current gaps:

• The local panel registry has Image Preview, Audio Preview, Video Preview, JSON, HTML, Table, Logs, and Artifact Inspector, but no 3D viewer panel.
• OpenAI shut down its Videos API and Sora 2 models on September 24, 2026, and lists no replacement. OpenAI therefore has no currently available video-generation endpoint for this pipeline; use another provider for video generation.
• A useful 3D path probably needs a new media/artifact type for meshes or scenes, plus a Three.js-style preview panel that can render model/gltf+json, model/gltf-binary, OBJ, USDZ, or similar asset references.

Suggested direction:

Author 3D-capable graphs around generic artifact/media primitives first, then add a 3D Preview panel once we have a concrete provider or file format to target.
