This submission is based on this original implementation on Stack Exchange:https://mathematica.stackexchange.com/a/136500. AxisAngle uses the "Pixar method" to generate the orthogonal vectors needed to apply the Euler fixed point theorem for computing the axis-angle representation....
Axis-angle representationSurgical plannerBone shape regenerationCurrent external fixators for distraction osteogenesis (DO) are unable to correct all types of deformities in the lower limb and are difficult to use because of the lack of a pre-surgical planning system. We propose a DO system that ...
Given the Direction Cosine Matrix, I want obtain the rotation vector, i.e. the Euler axis/angle? This transformation is common in multi-body dynamics, but I cannot find this same functionality in either the Aerospace Blockset or the Aerospace Toolbox....
physically of the analytical Jacobian [4]. Another drawback concerned meaningful definition of the rotational part of the impedance with impedance (stiffness) control based on an operational equation, and they suffer from the occurrence of representation space formulation is that the rotational ...
The exponential map The angle-axis representation The angular velocityThese three concepts are all closely related, so to make sure we're all on the same page, this is exactly how I'm defining them:The exponential map: A specific function which takes a 3D vector and produces a rotation ...
Gets the absolute angular acceleration of the device in an axis-angle representation in units of radians per second squared. This acceleration is expressed in the supplied coordinate system, although the motion is measured relative to the user's surroundings. C# Copy public Vector3 Absol...
Angle Calculator and Further examples I have put ajava applet herewhich allows the values to be entered and the converted values shown along with a graphical representation of the orientation. Also further examples in 90 degree stepshere

In fact, there might be two 180 degrees rotations around different axes with the same effect, resulting in the singularity condition for the Euler axis and angle representation. It is also remarked that the inverse trigonometric function cos−1 returns two possible values of the Euler angle (i...
