The dataset WaterDropSmall includes simulations of dropping water to the ground rendered in a particle-based physics simulator. You can inspect the files on the Files menu on the Jupyter notebook.

The metadata.json file in the dataset includes the following information:

1. The sequence length of each video data point
2. The dimensionality, 2d or 3d
3. The box bounds, which specify the bounding box for the scene
4. The default connectivity radius, which defines the size of each particle's neighborhood
5. The statistics for normalization, such as the mean and standard deviation of the velocity and acceleration of particles

Each data point in the dataset includes the following information:

1. The type of the particles, such as water
2. The particle positions at each frame in the video
