WebFiltering. Let’s chose an atom try to apply a filter on it. We want try to reduce the signal to noise ratio, so we calculate the mean of the s/n for all atoms: Like in the paper we will chose window_length=100 and polyorder=2, it as a 9.63 dB signal to noise ratio, that is quite accettable, and apply the filter to all of the LENS trajectories. Web- In addition to spherical particles, OVITO can now display particles with cubic and square shape. This can be useful for visualization of large lattice systems, Ising models, etc. - OVITO can now import more than one dataset into the scene and display them side by side. january 9 2023 news
