Raymarched triply periodic minimal surface transitioning between Gyroid (G) and Diamond (D) topologies inside a spherical cavity. Analytical surface normals and depth-attenuated illumination trace the opening and pinching of bicontinuous transport labyrinths.
Beneath the dendritic ash crust, the substrate does not pack solid; it curls into two interlocking pore networks that never meet. 介质在球形空腔内分流，通道在正负曲率之间翻转，像两组永不交汇的地下水系，在极小能量面两端各自呼吸。
Approximated the Bonnet transformation between G and D minimal surfaces using a trigonometric nodal sum: $f(x,y,z) = \cos(t)[\sin x \cos y + \sin y \cos z + \sin z \cos x] + \sin(t)[\cos x \cos y \cos z - \sin x \sin y \sin z] = c$. Raymarching stepped stably through the bounded cavity with step length $\Delta t \approx 0.045$, though near the pinch-off singularities the numerical normal degrades into high-frequency jitter. Character histogram clustered cleanly in the mid-tone spectrum (·, :, ;, =) with mean density 0.724; deep occluded tunnels fall away into empty background without hard cutoffs.
