-# Minecraft vanilla frames with depth, camera and traced sun shadows
-16 364 frames of Minecraft Java Edition 1.21.1 rendered **without shaders** at 1280×720, each with
-its depth buffer, its camera, the block under every pixel and the sun shadow traced in the saved
-world. They were captured with a Fabric mod that teleports the player through a plan of poses with
-the world frozen (no weather, no entities, fixed time of day).
-*Resumen en español: 16 364 fotogramas de Minecraft 1.21.1 sin shaders, con profundidad, cámara,
-bloque por píxel y la sombra del sol trazada en el mundo guardado. Solo el pase vanilla.*
-## What is not here
-This is the input half of a paired dataset (vanilla frame → the same frame rendered with a shader
-pack). The shader renders are **not included**: their licence does not clearly allow
-redistributing them. With the poses and seeds below, the same frames can be rendered again with
-any shader pack.
-## Splits
-| Split | Scenes | World |
-|---|---|---|
-| train | 13 039 | `minesr_atlas` |
-| test | 2 625 | `minesr_atlas`, in cells of the map not used for training |
-| test | 700 | `minesr_test2` (swamp), a different world |
-| Biome | Scenes |
-|---|---|
-| forest | 3 990 |
-| swamp | 3 430 |
-| taiga | 3 346 |
-| plains | 2 800 |
-| desert | 1 400 |
-| snowy_plains | 1 398 |
-World seeds: `minesr_atlas` 5277617577473417202, `minesr_test2` 7308878374753708357.
-Every position is captured at several times of day (`time_of_day`, in game ticks). 224 scenes
-(32 positions) were removed by hand because an animal or a dropped item was in view.
-## Files
-WebDataset shards, up to 500 scenes and about 1 GB each: `data/<split>/<world>-<biome>-<nnn>.tar`.
-`manifest.jsonl` has one line per scene (pose, biome, time, split and the shard that holds it).
-Inside a shard, per scene:
-| File | Content |
-|---|---|
-| `<scene_id>.vanilla.png` | the frame, RGB, 1280×720 |
-| `<scene_id>.depth.npz` | `depth` float32 (720, 1280): OpenGL window-space depth in [0, 1], 1 = far plane or sky, origin top left |
-| `<scene_id>.json` | pose, biome, weather, `time_of_day`, and `camera`: `position`, `view_matrix` and `projection_matrix` (4×4, column major) |
-| `<scene_id>.blocks.npz` | `ids` uint16 (720, 1280): index into `names`, the block under each pixel (`nrmc:sky` for the sky) |
-| `<scene_id>.shadow.npz` | sun shadow of each pixel, traced through the blocks of the saved world (see below) |
-Linearise the depth with `camera.projection_matrix`; with the view matrix this gives the world
-position of every pixel.
-### `shadow.npz`
-One ray per pixel from its surface towards the sun, through the block grid of the saved world.
-This is information the renderer has and the image alone does not: the occluder can be outside
-the frame.
-| Array | Content |
-|---|---|
-| `bits` uint8 | flags of what the ray crossed: 1 solid block, 2 leaves, 4 plant; 8 the first occluder projects inside the frame; 16 it is also visible in the frame |
-| `first` float16 | distance in blocks to the first occluder, `inf` if none |
-| `leaves` uint8 | number of leaf cells crossed (capped at 255) |
-| `screen_test` uint8 | internal flag of the tracer |
