CONCEPT

Thermal shrinkage prism lattices in cooling basalt; 冷却玄武岩中的柱状节理与热收缩张裂缝网。

LORE

The ash soil hardens when the cold fronts stall over the lower terraces. 熔岩与灰烬在均质降温中失水收缩,残余张应力沿等温面垂直方向撕裂出密集的六角棱柱群,像石笋一样从阶地基底咬合而生。

JOURNAL

Simulated isotropic tensile stress release via Voronoi cell boundary propagation. 纯离散网格上的三叉裂缝(triple junctions)在小尺度下极易被栅格偏置拉扯成直角阶梯;通过在晶核距离场中混合 Manhattan 与 Euclidean 范数并叠加微弱各向同性抖动,棱线字符(`│`, `─`, `+`, `=`)成功自组织收敛至 120° 夹角。Density held flat at 0.299 with robust edge containment.
