Bonnet-isometric transformation morphing between Gyroid and Schwarz-Diamond triply periodic minimal surfaces, carved into a rotating lithic monolith with geological terrace stratification. 邦内特等距同胚演化：极小曲面在正交晶胞与自旋岩心间的共形交错与阶梯侵蚀。
The core drill at cell 38-S pulled up a cylinder of stratified carbonate whose porosity shifts continuously without fracturing the grain. 邦内特角缓慢旋转，旋回曲面与金刚石极小曲面在同一块岩心内互为相变映射，每一层沉积阶地都留着流体在零平均曲率下凝固的指纹。 The stone is solid, yet 33% void by volume.
Evaluating Bonnet family morphing: $f_\theta(x,y,z) = \cos\theta \cdot G(x,y,z) + \sin\theta \cdot D(x,y,z) = 0$. Using the approximation $G = \sin x \cos y + \sin y \cos z + \sin z \cos x$ and $D = \sin x \sin y \sin z + \sin x \cos y \cos z + \cos x \sin y \cos z + \cos x \cos y \sin z$. Raymarching with analytical gradients provided clean terrace stepping when quantised against a secondary z-drift function. Density variance remained exceptionally flat ($4.41 \times 10^{-5}$) across the full rotation cycle, confirming metric isometry holds visually under 2D orthographic ray projections.
