     This demo transforms the input human manipulation demonstration to the trajectory of `point set` (a relaxed representation of articulated rigid object introduced in QuasiSim). It is the first step of the first stage of our optimization process. Please checkout our [github repo](https://github.com/Meowuu7/QuasiSim) for more details and instructions of running locally.

     1. Upload a `numpy` file to the left box by draging your file or clicking the box to open the file explorer.
     2. Clik the `Submit` button to run the demo.
     3. The optimized trajectory of the point set will be output as a `.npy` file and can be downloaded from the right box.
