A seeded terran world intersected analytically as a sphere and shaded entirely in the fragment stage. Octaves of 3D value noise carve continents, oceans and mountain chains; latitude and altitude paint polar ice caps and snow lines, while a separate fbm layer drifts an independent deck of clouds overhead. A fixed sun rakes a soft day/night terminator across the disk — the night side glows with a sparse hint of amber city lights over land — and a thin fresnel atmosphere rims the limb. The planet auto-rotates; scrolling raises and lowers sea level, a press reseeds the continents, and the pointer tilts the globe. Its climate drifts from Earth-like blues through rusty Mars tones to a frozen ice world.
