Learn to visualize 3D rotations using quaternions in VPython with this comprehensive tutorial. Explore the concepts of imaginary numbers, quaternions, and their application in simulating rigid body rotations. Discover how to integrate Arduino and the Adafruit BNO055 IMU sensor to capture real-time quaternion data. Master the process of converting quaternions to Euler angles and implement smoothing techniques for improved visualization. Gain hands-on experience in Arduino coding, Python programming, and data transmission between devices. Delve into advanced topics such as calibration, error handling, and optimizing the visual display for a more immersive experience.
