+**NEW**: The project now implements the paper ["Weighted Laplacian Smoothing for Surface Reconstruction of Particle-based Fluids" (Löschner, Böttcher, Jeske, Bender; 2023)](https://animation.rwth-aachen.de/publication/0583/). 
+It proposes a fast smoothing approach to avoid the typical bumpiness of the surfaces reconstructed from SPH simulations while preventing loss of volume for splashes and droplets that occurs with simple, non-speaclized smoothing methods.
+The images below show a rendering of a typical surface reconstruction (on the right) with visible bumps due to the SPH particles compared to the same surface reconstruction with weighted smoothing applied (on the left):

+You can see this rendering in motion in [this video](https://youtu.be/2bYvaUXlBQs). For more details see the [paper](https://animation.rwth-aachen.de/publication/0583/) and the [readme](https://github.com/InteractiveComputerGraphics/splashsurf) in the repository.

 This project consists of the following crates:
  - `splashsurf`: Binary crate with a CLI (command line interface) to quickly run surface reconstructions of SPH particle data files from the terminal
  - `splashsurf_lib`: Library that implements the reconstruction pipeline used by the CLI. Allows to integrate the reconstruction procedure directly into other Rust applications. Furthermore, it resembles a framework providing access to individual building blocks to create your own surface reconstruction pipeline.
