Ovito - Top

When looking down the Z-axis, combining the Top view with a or Common Neighbor Analysis (CNA) modifier reveals crystalline phases cleanly. For instance, in a FCC crystal lattice, a top view down the [001] direction showcases a square lattice grid, while the [111] direction highlights a hexagonal pattern. Color-coding atoms by their local coordination or CNA structural type allows amorphous or defective boundary regions to pop out sharply against the background.

The most common task in atomistic simulation is answering the question: "What is this?" Is the cluster of atoms crystalline, liquid, or glass? Moving from the bottom (atomic chaos) to the top (structural definition) requires robust algorithms.

So, why do researchers and scientists prefer OVITO over other data visualization and analysis tools? Here are some advantages:

When studying clusters, nanopores, or fractured surfaces, defining the boundary between "material" and "vacuum" is critical. This modifier uses an alpha-shape algorithm to construct a continuous topological mesh over the outer atoms, computing surface area and volume accurately. Wigner-Seitz Cell Analysis ovito top

Set the slice plane normal vector to to align it parallel to the Z-axis.

The ultimate goal of using the viewport is often to generate clean, high-resolution figures for journal papers. Follow these steps to export a professional visual:
