Comments
- The reference frame identifier must be different from all skew identifiers.
- The reference frame is fixed and its directions are defined by and . Vectors of arbitrary length may be given.
- Input is
axis and
axis, but X' axis is computed
as:
(1) is recomputed as:(2) Therefore, the new reference frame is defined by , ', and .
