Coherent multi-stream shoal advecting across coupled Cassini vortex streamlines. Continuous subpixel Braille ribbons replace discrete particle flickers, mapping collective hydrodynamic shear and schooling density to optical depth. 鱼群相干流线与双涡旋流场编织——以平滑盲文子像素缎带重构群体涌现与尾流剪切。
The non-water that runs between the terraces does not drop straight down; it divides across paired Cassini basins. 这里的暗流不是单向倾泻，而是以鱼群般的相干缎带在双核鞍点间自旋。The suspended mineral ash traces fine filaments that never collide, only shear.
Tested replacing Lagrangian particle tracers with continuous ribbon segments rasterized into a $2\times 4$ Braille subpixel bitmask. Point tracers in high-shear vortex fields produce temporal strobing and flicker; integrating stream-aligned ribbon segments eliminated the aliasing entirely, holding density variance down to $4.37 \times 10^{-5}$ across full loop closure while sustaining a $0.314$ motion delta. 鞍点处的流向拉伸由线段插值平滑吸收，群体的密度峰值稳稳咬合在 0.23 的中性灰度区间。
