Question about adjusting the spatial relationship of objects

[zoeyliu1999]

Dear authors, thank you for your excellent work!

I am trying to render a specified layout of furniture but am having trouble with HOLODECK understanding the spatial relationships. I am confused about how to correctly input this information or modify it directly in the file.

For example, my query is: "a rectangular bedroom with tiled flooring and large windows on one side. Place the bed against the wall opposite the windows, the wardrobe to the right of the bed, and the desk with a chair near the windows." However, the generated layouts always place the bed incorrectly, as shown in the attached pictures.

How can I adjust this? Should I refine my query, or directly modify the positions in the .json file? Which method would be more effective? Any suggestions or guidance would be greatly appreciated. Thank you!

Hey there, I wanted to add some new information. When I regenerated the scene using a query with a specific orientation, such as "large window on the east wall" and "place the bed against the west wall, opposite the window," HOLODECK performed better. The result, as shown in the attached image, was different from what I initially expected but a significant improvement over the previous query.

Can I directly edit the room's size or object positions in the .json file? The .json file looks like this:

"objects": [
        {
            "assetId": "Bed_9",
            "id": "bed-0 (bedroom)",
            "kinematic": true,
            "position": {
                "x": 1.2107633399963378,
                "y": 0.6772908568382263,
                "z": 1.5
            },
            "rotation": {
                "x": 0,
                "y": 90,
                "z": 0
            },
            "material": null,
            "roomId": "bedroom",
            "vertices": [
                [
                    246.65266799926758,
                    41.439504623413086
                ],
                [
                    246.65266799926758,
                    258.5604953765869
                ],
                [
                    -4.5,
                    258.5604953765869
                ],
                [
                    -4.5,
                    41.439504623413086
                ]
            ],
            "object_name": "bed-0",
            "layer": "Procedural0"
        },

Is it effective to edit the position details in the above "Bed_9" entry? Additionally, I couldn't find the parameters to control the room size. Any suggestions or guidance would be greatly appreciated.

I apologize for mistakenly closing the issue. It is still open.

We did not consider the fine-grained spatial relation between objects and walls (only consider the non-collision and within the boundary for walls).

However, the DFS constraints solver can return multiple solutions, and you can choose from them.

You could also refer to this function which will rerun the DFS solver and give you a different layout using the same set of objects.
