Large Scale Structure — ΛCDM
Interactive visualization of large-scale cosmic structure based on ΛCDM cosmology. Simulates galaxy cluster nodes with NFW dark matter halo profiles, Bézier-curved dark matter filaments with baryon streaming, cosmic voids, and baryonic sheet/wall particles. Quasars (AGN) rendered as high-mass nodes. FBM density field drives node placement via Zel'dovich approximation.
