## FluidNexus-Smoke and FluidNexus-Ball
Our FluidNexus-Smoke and FluidNexus-Ball datasets each include 120 scenes. Every scene contains 5 synchronized multi-view videos, with cameras arranged along a horizontal arc of approximately 120°.

* **FluidNexusSmoke** and **FluidNexusBall**: Processed datasets containing one example sample used in our paper.
* **FluidNexusSmokeAll** and **FluidNexusBallAll**: All samples processed into frames, usable within the FluidNexus framework.
* **FluidNexusSmokeAllRaw** and **FluidNexusBallAllRaw**: Raw videos of all samples as originally captured.
* **DATASETNAME_cogvideox_dataset**: These processed datasets, ready for direct use in [`CogVideoX`](https://github.com/THUDM/CogVideo) training and inference, include labels generated by [`CogVLM`](https://github.com/THUDM/CogVLM).

For more details, please refer to our [project page](https://yuegao.me/FluidNexus/), [code repository](https://github.com/ueoo/FluidNexus/), and our [paper](https://arxiv.org/abs/2503.04720).

## ScalarReal
We also used the **ScalarFlow** dataset. Here, we provide one sample from it, ScalarReal. Please refer to the ScalarFlow [website](https://ge.in.tum.de/publications/2019-scalarflow-eckert/) for more information.
