| # MultiView-Bench | |
| Evaluation data for **MultiView-Bench: A Diagnostic Benchmark for | |
| World-Centric Multi-View Integration in VLMs** | |
| ([arXiv:2607.08970](https://arxiv.org/abs/2607.08970)). | |
| This repository currently contains the synthetic image-and-text portion of the | |
| benchmark. The real-world subset is not included; see the scope note below. | |
| ## Contents | |
| - 2,400 evaluation samples across 24 benchmark variants | |
| - 7,900 PNG views (2.94 GiB logical image data) | |
| - One, three, or six images per sample | |
| - English question text and deterministic coordinate answer | |
| - Single-agent and multi-agent question schemas | |
| The `3D Real World` / `exp3D_real_world_50` subset is intentionally excluded. | |
| It uses 3DCoMPaT++ source assets and is not part of this release. This package | |
| also contains no GLTF, BIN, model asset, source code, credentials, or model | |
| outputs. | |
| ## Task previews | |
| Each sample asks for a relative 3D position and must be solved by integrating | |
| the evidence across its views. | |
| ### Colored-object three-view task | |
| **Question:** What is the relative position of the olive cone to the indigo | |
| cube? | |
| **Answer:** `(-X, -Y, -Z)` | |
| | Front | Side | Top | | |
| |:---:|:---:|:---:| | |
| |  |  |  | | |
| ### 3D isometric task | |
| **Question:** What is the relative position of the cylinder to the cone? | |
| **Answer:** `(0X, 0Y, -Z)` | |
| The full sample contains six views; three are shown here. | |
| | View 0 | View 2 | View 4 | | |
| |:---:|:---:|:---:| | |
| |  |  |  | | |
| ### Full 3D reasoning (DoF=3) | |
| **Task variant:** `3D DoF=3` (unconstrained placement along X, Y, and Z) | |
| **Question:** What is the relative position of the cube to the cylinder? | |
| **Answer:** `(-X, +Y, +Z)` | |
| The full sample contains six views; three are shown here. | |
| | View 0 | View 2 | View 4 | | |
| |:---:|:---:|:---:| | |
| |  |  |  | | |
| ### Single-view 3D task | |
| **Task variant:** `3D Single View` | |
| **Question:** What is the relative position of the cube to the cylinder? | |
| **Answer:** `(-X, +Y, +Z)` | |
| Unlike the multi-view variants, this sample exposes only one isometric view. | |
|  | |
| ### Grid-assisted three-view task | |
| **Task variant:** `2D Three Views Grids` | |
| **Question:** What is the relative position of the cylinder to the sphere? | |
| **Answer:** `(0X, -Y, -Z)` | |
| The projected coordinate grids provide additional alignment cues in each view. | |
| | Front | Side | Top | | |
| |:---:|:---:|:---:| | |
| |  |  |  | | |
| ### Rotated-coordinate task (90°) | |
| **Task variant:** `2D Three Views Rotation (90°)` | |
| **Question:** What is the relative position of the cube to the cone? | |
| **Answer:** `(+X, 0Y, -Z)` | |
| The coordinate frame is rotated to test whether the model follows the visible | |
| axes rather than relying on a conventional orientation. | |
| | Front | Side | Top | | |
| |:---:|:---:|:---:| | |
| |  |  |  | | |
| ### Multi-agent three-view task | |
| **Task variant:** `2D Three Views multiagent (Rotation 0)` | |
| **Question:** What is the relative position of the sphere to the cone? | |
| **Answer:** `(-X, -Y, +Z)` | |
| Each view has its own axis-pair prompt (`front_question`, `side_question`, or | |
| `top_question`) so three view-specific responses can be combined into the | |
| full XYZ answer. | |
| | Front agent: XZ | Side agent: YZ | Top agent: XY | | |
| |:---:|:---:|:---:| | |

| ## Load | |
| After upload: | |
| ```python | |
| from datasets import load_dataset | |
| dataset = load_dataset("suijinru/MultiViewBench", split="test") | |
| sample = dataset[0] | |
| print(sample["benchmark"], sample["question"], sample["answer"]) | |
| print(sample["images"]) | |
| ``` | |
| For a local pre-upload check: | |
| ```python | |
| dataset = load_dataset("imagefolder", data_dir="test", split="train") | |
| ``` | |
| `ImageFolder` derives the `images` column from the `images_file_names` list in | |
| `test/metadata.jsonl`. The Hub recognizes columns ending in `_file_names` as | |
| image lists. | |
| ## Fields | |
| - `benchmark`: benchmark variant identifier | |
| - `task_variant`: human-readable task variant label used to group corresponding | |
| results in the paper; it is not a row number. For the 3D variants, DoF | |
| describes the object-placement constraint: DoF=1 restricts objects to the | |
| same axis, DoF=2 restricts them to the same plane, and DoF=3 allows | |
| unconstrained placement in 3D space. | |
| - `task_id`: task identifier within the variant | |
| - `mode`: `single` or `multi` | |
| - `question`: complete prompt for single-agent samples | |
| - `front_question`, `side_question`, `top_question`: per-view prompts for | |
| multi-agent samples | |
| - `answer`: expected coordinate answer | |
| - `images_file_names`: ordered relative paths to all views | |
| - `num_views`: number of views | |
| All rows are evaluation data; do not use them for training when reporting | |
| MultiView-Bench scores. | |
