cosmos
Pure astrometry + astrology engine — ephemeris, sky, sundial, tides, transits — in Rust, with a Llimphi UI.
cosmos computes the sky. Around a core astrology engine sit independent astrometric extracts — cosmos-ephemeris, cosmos-sky, cosmos-sundial, cosmos-tides, cosmos-transits, cosmos-pointing — that serve sundial / tides / navigation / planning without touching the chart machinery. A GPU UI (cosmos-app-llimphi, cosmos-canvas-llimphi) renders charts, sky maps and a dense starfield.
Run
cargo run --release -p cosmos-app-llimphi # the chart/sky desktop app
cargo run --release -p cosmos-canvas-llimphi --example dense_starfield
How dependencies work
cosmos is a full app: its UI integrates notebooks, panels and content-addressed sources. Llimphi and every foundational dependency are pulled as git dependencies from the gioser monorepo — the suite's source of truth. The astrometric core crates (cosmos-ephemeris, -coords, -time, …) are pure compute with no UI deps.
