低多邊形小島上的風車

Create a 6-frame looping 3D low-poly sprite sheet, 3 columns by 2 rows of equal 512x512 cells on a flat sky-blue background. Subject: a tiny floating low-poly island with grass, one white windmill and two small trees, seen from the same isometric camera in every cell. Only the four windmill blades rotate, by 15 degrees clockwise per cell, so that six cells complete a 90-degree repeat and frame 6 flows into frame 1. The island, trees and shadows do not move. Flat-shaded facets, soft shadow. No grid lines, no numbers, no text.

生成 6 幀迴圈 3D 低多邊形精靈圖，3 列 2 行，每格 512x512，純天藍背景。主體是一座漂浮的低多邊形小島，有草地、一座白色風車和兩棵小樹，每格都是同一個等距機位。只有四片風車扇葉轉動，每格順時針轉 15 度，六格轉完 90 度，第 6 幀接回第 1 幀。小島、樹和影子都不動。平面著色的稜面，柔和陰影。不要格線、數字和文字。
