Rotation matrices change the orientation of a vector or object without changing its length, angles, or shape. A rotation about one coordinate axis leaves that axis unchanged while mixing the other two coordinates through sine and cosine. Every proper rotation matrix is orthogonal, satisfying R^{T}R=I, with determinant +1. Its inverse is therefore its transpose. Rotations about several axes are combined through matrix multiplication, but their order matters because three-dimensional rotations generally do not commute. These matrices are used to orient cameras in computer graphics, control robotic arms, track spacecraft attitude, transform coordinate systems, and estimate the pose of objects in computer vision.
