turn: 1
modality: image
input: text: Based on the provided empty room scene image, please place the following three pieces of furniture side-by-side horizontally within the main space of the room: a vending machine, a public bench, and a trash can. Ensure there is some space between them so they do not overlap or block each other.
output: evaluation_points: 1. The image must clearly contain one instance each of a vending machine, a public bench, and a trash can.

2. All three pieces of furniture must be arranged horizontally (left-to-right), not stacked or placed in a front-to-back line.

3. All other background elements must match the original empty room reference image.

4. The image must clearly appear to be a modification of the reference image (e.g., objects added to an existing scene), not a completely newly generated room.

turn: 2
modality: text
input: Observe the image generated in the previous turn. Among the three newly added pieces of furniture, which one is positioned in the middle?
Options:
A. Vending machine
B. Public bench
C. Trash can
D. None of the furniture is in the middle
E. None of the above.
output: answer: <DYNAMIC>

turn: 3
modality: image
input: Please remove the tallest piece of furniture from the three newly added in the previous image. Keep all other elements unchanged.
output: evaluation_points: 1. The visually tallest piece of furniture (the vending machine) must be removed, leaving that area blank or revealing the background.

2. The positions and appearances of the two remaining pieces of furniture (the bench and trash can) must not change.

3. The background and all other elements must remain consistent with the Turn 1 reference image.

The background and all other elements must remain consistent with the Turn 1 input image.

turn: 4
modality: image
input: Based on the image from the previous turn, reposition the two remaining pieces of furniture so they are aligned strictly along a single vertical (front-to-back) line. Place the shorter piece of furniture in front and the taller piece behind it, creating a correct visual occlusion relationship where the front object partially blocks the view of the back object. Keep all other environmental elements unchanged. Please generate the adjusted room layout.
output: evaluation_points: 1. The image must contain only the two remaining pieces of furniture (bench and trash can). The removed vending machine must not reappear.

2. The two pieces of furniture must be aligned along a single front-to-back axis, not offset left or right from each other.

3. The shorter piece of furniture (the trash can) must be placed in front, and the taller piece (the bench) must be placed behind it.

4. The front furniture must visually occlude part of the rear furniture, creating a clear foreground/background relationship.

5. The style and size of the furniture must remain the same; only their positions and depth relationship should change.

6. The room background must match the reference image, and the image should appear as a continuous modification from the previous steps.
