Battle of Dan-no-ura as a 3D battle map

A 74-second 3D reenactment of the 1185 naval Battle of Dan-no-ura in the manner of a TV history special: terrain, fleets, advance arrows, fog, and the turning tide of the Kanmon Strait. Opus 5.5 built it from a four-line Japanese prompt.

How it was made

The prompt asks for a 3D overhead "demo", and the creator's thread says it has adjustable playback speed, switchable viewpoints, and a tide that changes in real time. The agent and the 3D library aren't named.

Look notesby Reference

A low-poly 3D model of the Kanmon Strait, seen from overhead and at sea level, with red-flagged and white-flagged fleets (the Heike and the Genji), a tide gauge, and Japanese chapter titles over mist.

Color
Muted moss-green hills, slate-blue water, and white mist, with red and white for the two fleets and their arrows, and a warm peach sky in a late scene. The interface sits in dark translucent panels with red and white readouts.
Type
Large white Mincho-style kanji for chapter titles (早鞆の瀬戸, 布陣, 西流), smaller white captions with a line of explanation (潮が東へ流れ始める, 平知盛、入水), and tiny interface labels.
Framing
A broadcast-style overlay: a dial and two charts for the tide's direction and speed in a panel at top right, a playback timeline with speed buttons along the bottom, and captions at lower left. Views alternate between a top-down map with arrows and chevrons in the current, and low shots among the ships.
Structure
The misty strait titled 早鞆の瀬戸, the fleets in formation (布陣), the tide starting to run east as the red fleet advances, the eastward current at its strongest, the tide weakening, the current turning west (西流) behind the white fleet, the red fleet pushed back, Taira no Tomomori's drowning at sunset, and the title again.
