Show HN: Dyson Sphere simulation (C++/OpenGL)

3 corvo01 2 8/29/2025, 10:55:10 AM github.com ↗

I built a simple simulation of a Dyson Sphere using C++ and OpenGL. It renders ~20,000 satellites orbiting a star, with adjustable parameters like satellite size, density, and distribution.

The goal was to explore graphics programming and visualize how such a megastructure might look. It’s still work in progress, but functional enough to share.

pretty cool, kind of like the idea these sattelites would harness sun for propulsion too :) not sure if it would be more efficient than powering their own propulsion with the already captured energy (i know nothing about this obv)

i wonder a bit too, totally unrelated to the software engineering here. how would one get the power back to earth? :'? dont say photon rays :D but really how ?
