艦船と航空機が戦う第一次世界大戦のボクセル戦場シミュレーション

Build a World War One battlefield simulation in a voxel style that runs in the browser, preferably with Three.js. Show a square diorama of voxel terrain: muddy no-man's-land crossed by trenches, green fields, small villages with red roofs, a river and a coastline with a sea plane beside it. Populate it with warships, biplanes and ground forces that fight on their own, with shell impacts that blast voxels out of the ground and leave craters, smoke and debris particles. Provide an orbit camera the user can rotate and zoom, plus a small panel with a few simulation controls. Use a muted earthy palette against a pale blue sky. Deliver one self-contained HTML file. Done means the battle plays continuously, the terrain visibly changes under fire, and the frame rate stays smooth.
