Rings genuinely near the viewer appear larger - **Back-face culling** — segments behind the toroid midplane are skipped, not just faded - **Two-axis toroid tilt** — each ring has independent X and Z random tilt (precomputed trig), giving varied orientations - **Depth-sorted render order** — toroids sorted back-to-front each frame for correct visual layering ### Performance - **Segment batching** — 52 segments per ring grouped into 5 depth bands and drawn as 5 paths instead of 52 individual draw calls. Shadow blur applied only on the front 2 bands - **Proper dt timing** — lightning accumulator uses real frame delta time instead of hardcoded 16ms ### New Visual Features - **4 color themes** — Plasma, Amber (ROOT0 palette), Solar red, Void green. Toroid colors re-tint when switching - *
