A new fortran-90 library for 3D rotation conversions

This page describes a fortran-90 module, rotations3D.f90, that provides functions, both in single and double precision, to convert between seven different rotation parameterizations.  Fortran-90 source code implementing the 3D rotation conversion functions is available for download (zip file containing the 3Drotations module, along with an example program and associated input file).   3D rotations are frequently needed …

Cubochoric coordinates: a new parameterization of 3D rotations

The contents of this page were extracted from a manuscript in press in Modeling and Simulations in Materials Science and Engineering (MSMSE).  Contact M. De Graef for additional information.    Fortran-90 source code that implements this rotation parameterization is available for download (zip file containing so3-sampler.f90; compiles with gfortran).  This program asks the user for a sampling …
