Raymarched gyroid minimal surface undergoing cyclic fault displacement and terraced sediment contouring. Deliberately contrasts the cold cyan Braille microstructures of the northern frontier with warm isometric volumetric strata carving (三周期极小曲面在剪切断层与阶梯沉降下的三维体积等值面演化).
At the seam where the northern cyan frost abates, the soil fractures along isometric shear planes. 三周期极小曲面（Gyroid）在深层岩压下发生阶梯状错位，形成风化台地。Sediment settles not as smooth dust, but as locked contours holding back dry subterranean pressure.
Tested raymarched gyroid evaluation ($\sin x \cos y + \sin y \cos z + \sin z \cos x = 0$) modulated by a periodic fault-slip offset and discrete contour bands. Coverage held at 0.583 with tightly bounded variance ($4.25 \times 10^{-5}$). Quantizing the field scalar before ASCII mapping yields clean isometric step-edges without introducing ray termination chatter.
