Blazing Fast Cubic Bézier Easing Function Library in C++

This article introduces a single-header C++20 library that represents cubic Bézier curves directly as easing functions, leading to performance improvements in animation. Implemented using the `EasingCubicBezier` template class, the library offers PRECISE (high accuracy) and FAST (high performance) modes. Benchmark tests demonstrate that this approach outperforms Blender's algorithm and numerical solutions based on the Newton-Raphson method, offering superior speed and stability, especially for real-time animation systems. This is because it avoids the overhead of solving cubic polynomial equations at runtime.
