Скачать или смотреть Mastering 3D Rotations: Rodrigues' Rotation Formula Explained | Finite Rotation Series (Part 3 of 4)

🚀 Welcome to Part 3 of our four-part mini-series on handling 3D finite rotation in geometric nonlinearities! 🚀

In this video, we break down Rodrigues' Rotation Formula, an elegant and computationally efficient method for handling 3D rigid body rotations using just an axis and an angle. Unlike Euler angles, this approach avoids gimbal lock while being more intuitive and efficient than the Direction Cosine Matrix (DCM).

📌 What You'll Learn:
✅ The fundamentals of Rodrigues' Rotation Formula and its real-world applications
✅ How to represent 3D rotations using an axis and an angle
✅ The step-by-step derivation of Rodrigues' Rotation Formula
✅ Why this method is more efficient than Euler angles & DCM
✅ The geometric interpretation of 3D rotations
✅ When to use Rodrigues' formula vs. other rotation methods

📌 Who is this for?
This series is perfect for engineers, aerospace professionals, robotics enthusiasts, and structural analysts looking to gain a deeper understanding of 3D finite rotations!

🛠 What's Coming Next?
👉 Stay tuned for Part 4, where we explore Quaternions, the final and most robust method for 3D rotations!
