### Benchmark example
For example:
```
splashsurf reconstruct data/canyon_13353401_particles.xyz --output-dir=out --particle-radius=0.011 --smoothing-length=2.0 --cube-size=1.5 --surface-threshold=0.6
splashsurf reconstruct canyon_13353401_particles.xyz -r=0.011 -c=1.5 -l=2.0 -t=0.6 --subdomain-grid=on
```
With these parameters, a scene with 13353401 particles is reconstructed in less than 3 seconds on a Ryzen 9 5950X. The output is a mesh with 6023244 triangles.
