🥉 Meta 标志与 Besace 曲线拟合
Quoting Kyle Ferrana — simonwillison.net · 05-27 06:41 · 🔒 安全
Meta 公司的标志实际上是一条 Besace 曲线，其隐式方程为 (x² + y²)² = a²(x² - y²) + b²y²，参数形式涉及三角函数。文章提出如何从给定的标志图像中反推参数 a 和 b 以精确拟合曲线。通过最小二乘法或几何约束，可以将标志上的采样点代入方程求解。作者还讨论了 Besace 曲线的数学性质及其与 Meta 标志的视觉相似性。结论是：利用参数化曲线拟合技术，可以逆向工程出品牌标志背后的精确数学表达式。
💡 为什么值得读: 如果你对数学曲线拟合、品牌设计中的几何美学或逆向工程感兴趣，这篇文章用简洁的推导展示了如何从视觉标志反推数学参数。
