  the Origin Goal: Rotate a vector v = (x;y;z) about a general axis with direction vector br (assume bris a unit vector, if not, normalize it) by an angle (see –gure 9.1). Because it is clear we are talking about vectors, and vectors only, we will omit the arrow used with vector notation.

  Rotation matrix From Wikipedia, the free encyclopedia In linear algebra, a rotation matrix is a matrix that is used to perform a rotation in Euclidean space. For example the matrix rotates points in the xy-Cartesian plane counterclockwise through an angle θ about the origin of the Cartesian coordinate system. To perform the rotation, the position of each point must be represented by a column ...
