The Explicit Expression of Axis and Angle of a Rotation Matrix

For any matrix in the rotation group SO₃, we give the explicit expression for its axis and angle of rotation without computing eigenvectors. The formulas depend only on the entries of the matrix, ...

Infill and bridges rotation with model by Z-axis // External briges direction by shortest side/path

Is your feature request related to a problem? When I have to rotate the part on the bed along the Z axis, the direction of infilling and bridges do not change and remain global. This is not very ...

Alternating Iterative Optimization With Matrix Decomposition for Calibration-Free Rotation Angle Estimation and Polarization Reconstruction

Abstract: Accurate estimation of rotation angles in polarimetric imaging is critical for high-precision polarimetric measurements. While existing least-squares-based methods avoid complex instrument ...
