3D Rotations and Quaternions vs MakesSense

3D Rotations and Quaternions is an interactive tool for users who work with 3D orientation math in graphics, roboticsor simulation. It provides precise computations, clean visualizations, and fast conversions between the standard rotation representations. Features include: • Conversion between Euler angles, axis–angle, quaternions, and rotation matrices • Interactive 3D visualization and rotation animation • Quaternion interpolation (LERP and SLERP) • Rotation of user-defined points by user-defined quaternions • Determination of a quaternion that rotates vector v into vector w • Composition of up to 10 sequential quaternion rotations • Quaternion generation from constant angular velocity and time • Reflection of a point across a plane Feedback and suggestions: graphmath@aol.com

MakesSense — the math app that actually teaches. Other apps give you answers. MakesSense shows you how — step by step, in plain language, with the exact transformation and why it works. From Basic Math through Quantum Physics, every problem is broken down into clear, structured steps so you never feel lost. No skipped logic. No black boxes. Just math that finally clicks. Basic Math is free, with no time limit.
