# Particle Component

The Particle Component (cee::pt) provides support for time-stepped particle simulation data. It can open pre-computed particle datasets in PTFX and VTP formats, iterate over frames, query scalar fields, and write PTFX files. Custom file formats can be added at runtime via reader plugins or by providing a custom `ParticleDatasetReader`.

The `ParticleModel` is a full `vis::Model` and can be added directly to a `View` for rendering.
