Comments
- For fixed skews, the skew system is fixed and is defined by and . Vectors of arbitrary length may be given.
- For a fixed skew, inputs are
axis and
axis, but
axis is computed as:
is recomputed as:
- The new fixed skew is defined by , and .
- The skew origin O' is useful when
defining some condition with respect to the skew in cylindrical coordinate system.
