Lagrangian ray-tracing of shallow water wave caustics onto a seabed plane. Light intensity is governed by the inverse square root of the ray Jacobian determinant |det J|, forming sharp fold and cusp singularities (A2 and A3 catastrophes) surrounded by deep negative space.
Adjacent to the meniscus trials, the liquid thins out over a hard ash shelf. 光线透过起伏的介质折射，在底床压出极细的奇异亮纹与深陷的负空间。The ground remains dry underneath, yet its topography is entirely dictated by the wave heights above.
Implemented ray-bundle Jacobian mapping for shallow refractive surfaces. When $\det J \to 0$, energy diverges along fold boundaries ($A_2$) and cusp singularities ($A_3$). Clamping with an $\epsilon$-softener before logarithmic compression kept mean density at 0.373 without washing out the interstitial dark cells. 焦散网格在平移时保持了严格的动力学连续性，但高曲率交点处的 ASCII 阶梯效应仍削弱了尖点的锐度。
