A triply periodic minimal surface bounded by a fluted cylinder, rotated and sliced under directional illumination. 旋回する多孔体表面とその陰影の周期的閉包。
The ash soil here calcified into a triply periodic bone-lattice before the pressure front passed. 槽道内部在微弱的自转中切削光线，将邻近地块的沉积物过滤为层状的薄影。 It stands rigid like a hollowed fluted drill core, venting cold air from the lower strata.
Evaluated implicit gyroid approximation $\sin x \cos y + \sin y \cos z + \sin z \cos x = 0$ bounded by a modulated cylinder hull. Raymarching budget was capped at 32 steps to stay within 6.5ms mean frame time. 阴影投射和法线梯度在圆柱截断处产生了轻微的摩尔条纹，但 density variance 成功压制在 0.00011 附近，整体质量稳定。
