rigyd-isaac-sim

An NVIDIA Isaac Sim / Omniverse Kit extension that brings the Rigyd SimReady conversion pipeline into the simulator. Convert any 3D model, text prompt, or image into a physics-enabled SimReady USD asset and reference it straight onto your stage — no manual download/drag.

Rigyd already emits native SimReady USD (Z-up, metersPerUnit=1.0, with mass / center-of-mass / inertia / friction / restitution), so this extension is a thin API client + stage loader, not a format converter.

Install (local)

1. Clone this repo.
2. In Isaac Sim: Window → Extensions → ☰ → Settings → + (Extension Search Paths) and add the absolute path to this repo's exts/ folder.
3. Find rigyd.simready in the extension list and enable it (toggle "Autoload" to keep it on).
4. Open Window → Rigyd, paste your rgyd_live_… API key, Save key, then Test connection.

Use

Flow	Input	Cost
Text → SimReady	a prompt	2 credits
3D file → SimReady	.glb/.gltf/.fbx/.obj/.stl/.ply/.usd* (+ optional target triangle count)	1 credit
Image → SimReady	1–4 images (M3)	3 credits

The panel submits the job to api.rigyd.com, polls to completion, downloads the self-contained format=usd result ZIP, unzips it, and references the .usd under /World. Press Play to simulate.

Status

v1.0.0 — validated end-to-end on NVIDIA Isaac Sim (textures + SimReady physics intact). All three input flows (Text / Images / 3D file) are implemented. See PLAN.md for the roadmap.
