This is the dataset for [SeeU: Seeing the Unseen World via 4D Dynamics-aware Generation](https://yuyuanspace.com/SeeU/).
## Dataset Structure
- `SeeU45_train/`
Provides the 2D frames used as model inputs during training.
- `SeeU45_GT/`
Contains the full scene ground-truth frame sequences.
- `SeeU45_GT/sample_frame.txt`
Specifies which frames are sampled for training. It also records:
- the original scene/video folder names,
- sampled frame indices,
- total frame counts (GT length),
- and frame numbers corresponding to `SeeU45_train` inputs.
