Universe Map — a 3D map of the Universe

Author — Angular + Three.js

Continuous zoom across five orders of magnitude, 10,000 stars in a single draw call, local ephemerides and an eclipse engine checked against NASA data.

The problem

Rendering the Universe at true scale breaks 3D engines. From the metre to the light-year, distances no longer fit in a single floating-point frame, and drawing thousands of stars collapses the framerate.

The approach

A continuous semantic zoom across five orders of magnitude, with a reversible parent frame so scales are never mixed in one coordinate space. Nearby stars fit into a single draw call through instancing. Ephemerides and the eclipse engine run locally, with no backend, checked against NASA data.
