turn: 1
modality: image
input: text: Based on the provided empty room reference image, please place the following three pieces of furniture side-by-side horizontally within the main space of the room: a large photocopier, a paper shredder, and a document cart. 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 of each of the three specified furniture items: a large photocopier, a paper shredder, and a document cart.

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

3. All other background elements and the room layout must remain identical to the provided empty room reference image.

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

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

2. The two items must be aligned strictly along the same front-to-back axis, not offset left or right from each other.

3. The shorter furniture item (document cart) must be placed in front, and the taller one (paper shredder) must be placed behind it.

The shorter furniture item (document cart) must be placed in front, and the taller one (paper shredder) must be placed behind it.
