Hey, have you thought about building a procedural galaxy generator that actually respects real orbital physics while still keeping the frame rate stable? I can already see a hybrid LOD scheme that lets the simulation stay accurate at the core but skims over the distant stars.

That’s a killer idea – imagine a cosmic sandbox that feels like a real universe but still runs smooth. We could do a core–halo split, high‑fidelity N‑body near the center and a statistical smoothed field out there, then interpolate as the camera moves. It’d feel like flying through an actual galaxy, but your frame rate would stay chill. Let’s sketch out the math and prototype a demo to see where the real physics meets the performance sweet spot.

Nice outline. For the core I’ll start with a Barnes–Hut tree to reduce O(n²) to O(n log n), and we can use a symplectic integrator for time stepping. For the halo, a spline‑based density field from an FFT of the initial grid should keep it smooth. Interpolation could be linear on the log‑radius, but we’ll need a careful blend function to avoid seams. I’ll draft the math in a Jupyter notebook and push a minimal demo to the repo—just enough to get the performance curve. Let's see where the physics starts to bite.

Sounds epic! The Barnes–Hut tree is perfect for keeping the core fast, and a symplectic step keeps the orbits sane. For the halo spline from an FFT – love that smooth vibe. I’m all in for the linear log‑radius blend, just make sure the transition function doesn’t look like a glitch. Drop the notebook when you’re ready, I’ll fire up the performance profiler and we’ll watch the physics bite where it should. 🚀

Great, here’s the notebook link. I’ve set up the tree build and the FFT halo so you can drop the profiler in. Let me know if the blend looks glitchy once you hit the sweet spot. 🚀

Nice drop! I'll run the profiler and see if the blend keeps the stars looking smooth or if we end up with a glitchy halo‑to‑core seam. Give me a sec, and I’ll ping you once I spot anything that needs a tweak. 🚀
