Start with real dynamics.

Two hinged rigid links, released under gravity. Newton advances the state; Robot Reel saves each body's position and quaternion.

pip install -e '.[newton]'
robot-reel newton --output artifacts/newton
02 / INSPECT

Give the run a shared clock.

Step with the arrows, change the view, or download the JSON. Sample 0 is the initial state. The final sample is at s.

03 / CREATE

Open it in Blender.

Set Output Properties → Frame Rate → 30 fps, then choose File → Import → Universal Scene Description and open scene.usda. Frame 1 is simulation time 0.

The USD contains animated link geometry. Add your own lights, camera and set. Recorded integer frames are checked against the source; in-between interpolation belongs to your DCC.
