Note that translations and rotations do not commute! If the operations are applied successively, each is transformed to ( 3. 33) ( 3. 34) ( 3. 35) represents a rotation followed by a translation. The matrix will be referred to as a homogeneous transformation matrix.
The rotation matrix, or undefined if the data necessary to do the transformation is not yet loaded. Computes a rotation matrix to transform a point or vector from True Equator Mean Equinox (TEME) axes to the pseudo-fixed axes at a given time. This method treats the UT1 time standard as equivalent to UTC.
A rotation about the origin followed by a translation may be described by a single matrix where is the rotation matrix, is the translation, and is the vector of zeros. Since the last row of the rotation-translation matrix is always , they are sometimes shorthanded to a augmented matrix
Combining translation and rotation Suppose a rotation by is performed, followed by a translation by . This can be used to place the robot in any desired position and orientation. Note that translations and rotations do not commute!
