getTrafoRotaxis

compute a 4x4 Transformation matrix for rotation around an arbitrary axis

A toolset for Geometric Morphometrics and mesh processing. This
includes (among other stuff) mesh deformations based on reference points,
permutation tests, detection of outliers, processing of sliding
semi-landmarks and semi-automated surface landmark placement.

<dl><dt>pt1</dt>
<dd>numeric vector of length 3, defining first point on the rotation
axis.</dd>
<dt>pt2</dt>
