## Scenes: FIORD and FullCircle
Each folder `<Dataset>_<Scene>/` holds one scene reconstructed over the full fisheye field of view
(FIORD 200 degrees, FullCircle about 205 degrees per lens), as evaluated in the GOFish paper.
| Folder | Contents |
|---|---|
| `gaussians/` | GOFish (Ours): the Gaussian Splatting scene trained without SOF's geometry losses. Used for all rendering results. |
| `gaussians_geo/` | GOFish + Geometry Objective: the same pipeline with SOF's geometry losses. |
| `mesh/` | The + Geometry Objective mesh used in the paper's mesh results, as binary PLY and Draco-compressed GLB. |
| `cameras.json` | Calibration (OpenCV fisheye model) and every train/test camera pose. |
| `lidar_alignment.json` | FIORD geometry scenes only: the similarity transform into the LiDAR ground-truth frame used for the paper's mesh scores. Corridor_Out has none because its SfM-LiDAR registration is invalid, so the paper evaluates it for rendering only. |
## Download
Download one scene, or omit `--include` for all of them:
```
hf download AllenTu/GOFish-scenes --repo-type dataset --include "FIORD_Kitchen_In/*" --local-dir GOFish-scenes
```
## Formats
- `gaussians*/point_cloud.ply`: standard 3D Gaussian Splatting (INRIA) layout: `x y z nx ny nz f_dc_0..2 f_rest_0..44 opacity scale_0..2 rot_0..3`.
Opacity is a logit (apply sigmoid), scales are log (apply exp), rotation is a quaternion w,x,y,z, colors are degree-3 spherical harmonics with channel-major `f_rest`.
The GOFish 3-D Mip filter is baked in: each stored scale is `sqrt(scale^2 + filter_3D^2)`, so the file is exactly the stored scene GOFish renders and meshes.
Opacity is not rescaled, matching GOFish.
- `gaussians*/appearance.json`: the PPISP sensor model and GOFish's wide-angle attenuation W. This covers per-image exposure and color, per-camera vignetting, the camera response function, the radial profile and flat field, and the novel-view controller weights. Tensors are flattened row-major with their shapes.
Generic viewers ignore this file, so they show the scene's radiance without the camera's exposure and lens falloff.
- `mesh/mesh.ply`: the mesh exactly as evaluated, byte-identical to the paper's file. `mesh/mesh.glb` is the same mesh with Draco compression (KHR_draco_mesh_compression, 16-bit positions) for web viewers.
- `cameras.json`: COLMAP convention, `x_cam = R(q) x_world + t`, with `camera_to_world` given as its inverse. Intrinsics are at the stored image resolution. GOFish trained on images downsampled by 4, so divide fx, fy, cx and cy by 4 for the training resolution.
Gaussians, mesh and cameras share one world frame, the training COLMAP registration, with no normalization.
## Viewing
- Gaussians: SuperSplat (https://superspl.at/editor), gsplat, Nerfstudio or any 3DGS PLY viewer. These render with a pinhole projection. GOFish's full-FoV fisheye rendering needs the GOFish/3DGUT renderer with `cameras.json` and `appearance.json`.
- Mesh: MeshLab, Blender or Open3D for `mesh.ply`; three.js, Babylon.js or a glTF viewer with Draco support for `mesh.glb`.
`MANIFEST.json` in each folder lists every file with its size and sha256, and each scene's `README.md` gives its counts and provenance.
