The chair rotates like a turntable
Change only the fixed-chair sentence to its orientation relative to floor seams; keep the short camera arc.
Task template
Small camera arc around a chair: trace all four floor contacts
Keep one chair grounded while the camera moves along a short arc at constant height. This original exercise has not been model-tested and does not recover exact three-dimensional furniture geometry.
Includes original practice inputs and a review checklist. This prompt has not been independently tested with the generation model.
Download the input image below and upload it manually in the generator; the button carries the prompt.
01Prepare the inputs
- Use a three-quarter chair image with all four leg tips identifiable, including the rear pair. The supplied chair uses thin separated legs and a visible floor grid.
- Leave room around the chair so the arc does not crop a foot. If your source hides a leg completely, choose another view before asking to prove four contacts.
- Plan only a small view change toward the chair front. Do not demand a full orbit from a single illustration with an unseen back.
- Note each foot relative to nearby floor seams. Contact locations in the world should stay fixed even though their screen positions change with the camera.
02Prompt and procedure
Copyable prompt
Start from the uploaded chair scene. The single chair stays fixed on the floor with all four feet continuously planted. The camera moves slowly on a short smooth arc toward a slightly more frontal view, keeping the same height and a similar distance from the chair. The floor seams change perspective naturally with the camera. Keep the chair facing the same direction relative to those seams; it does not rotate on the floor. Preserve four legs, the connected seat and back, and coherent overlaps as the view changes. End with a still hold while the feet remain grounded. No chair slide, no folding, no new furniture, no zoom.
Map four feet before moving
Identify front-left, front-right, rear-left and rear-right tips in the source. Track them as parts of one chair, not as four marks that must remain at fixed screen coordinates.
Specify camera path and fixed chair
Ask for a short arc at constant height and similar distance. Name the chair orientation relative to the floor seams as fixed to distinguish the arc from a turntable effect.
Inspect changing overlaps
At mid-arc, trace each leg from its seat attachment to its foot. Some projected overlap can change; a new leg appearing, a tip floating or a leg merging into a seam fails the check.
Compare contacts at the ending
Use nearby floor seam intersections to judge whether the chair walked or slid. If the arc exposes too much unsupported geometry, reduce only the arc extent and repeat the four-foot trace.
03Check the result
- A single chair retains exactly four coherent legs.
- Every visible foot tip stays supported on the floor.
- Legs remain attached to the same seat structure.
- The chair keeps its orientation relative to floor seams rather than turning independently.
- Floor perspective changes coherently with the short camera arc.
- Seat and back connections do not fold, stretch or exchange sides.
- The final hold includes the full chair without foot cropping or continued drift.
04Troubleshoot and finish
A rear leg vanishes or duplicates
Reduce only arc extent so less unseen structure is exposed; trace the same rear leg again.
The feet float above the floor
Change only the contact requirement to all four foot tips continuously planted; inspect at mid-arc rather than just the ending.
The shot zooms into the seat
Change only the path description to similar camera distance and constant height, preserving space around every foot.
End on the slightly more frontal view with four grounded leg paths still traceable. Keep start, mid-arc and end contact notes; do not infer exact dimensions from the generated perspective.
