# DeVA — RoboCasa (processed)
Processed **RoboCasa** data for [DeVA](https://github.com/Mq-Zhang1/deva), a robot
video-world model with affordance + depth physical guidance. Derived from
[robocasa/robocasa](https://github.com/robocasa/robocasa) —
**please cite the original benchmark as well**.

`videos/` tiles the views on the grid given by `dataset_info.json::tile` — the
bottom-right cell is empty:
```
[[agentview_left, agentview_right],
[eye_in_hand, null ]]
```
## Affordance / depth `.npz`
Both are keyed by **canonical view name** (never by tile position), one array per view:
| | affordance | depth |
|---|---|---|
| key | `<view>` | `<view>` |
| dtype | `float16` | `float16` |
| shape | `[T, 224, 224]` | `[T, 224, 224]` |
| range | raw, un-normalized | `[0, 1]` |
| note | loader resizes to 128×128, then per-frame max-normalizes | per-view per-clip min-max applied at export |
`T` equals the episode's video frame count, so aux arrays index by absolute frame.
The validity mask is derived from the tile grid (`null` cells are invalid) and is not stored.
**Depth source** — DepthAnything (ViT-L) disparity, converted as `depth = 1 / disparity`;
**higher value = farther**. No percentile clip is applied: the range is set by the
farthest pixel, so agentview content occupies roughly the lower half of `[0, 1]` and
never saturates.
**Affordance source** — simulator oracle contacts rendered as Gaussian heatmaps.
